Three Points for Laser Purchaser

For most laser amateur, it is a haughty thing to own a special laser pointer, which is the new symbolize of fashion and cool among people, especially for school boys.  It is always a proud thing for a person to hold a laser device in hand, but it doesn't mean that we can always get the most satisfied laser. Price is not the only factor that customers should pay attention to, and the quality and applications are important tips that deserve our real attention. Enough knowledge is always necessary before purchasing and then you can really enjoy the fun of the laser. Faced with the huge but disorderly sales market, we must have a conscious to make distinguish between shoddy and genuine lasers.

1. Keep a sober mind against low price but shoddy laser.

There may have the following situation. In order to attract more customers, a small amount of manufactures of laser will provide retailers the shoddy laser products in low price with bad or used laser diode for the sake of reducing the production cost repeatedly. Even replace the high power laser with low output power. Sometimes even the retailers have also been cheat and in the dark. In the meantime, consumers are mainly puzzled by the low price and the products' outer packing. Well it is obvious that this part of package price is taken from your wallet. Therefore, for consumers, they should stay awake of that you want, a perfect and genuine laser products or a perfect outer packing but shoddy laser. The consumers should concentrate on the quality, performance, specification and customer service, etc.

2. Confirm what function of laser you need.

Laser has an extensive applied range for its high performance, such as industry, presentation, astronomy, military, entertainment, medicine, biology, cosmetology, energy exploitation, signal propagation and so on. In addition, in different fields, it needs different laser, which owns different function. So before you purchase an ideal laser product, you should make clear of what kind of laser you need. For example, for the most common industrial field, there may need alignment laser, or OEM laser for cut things or correct alignment. If you are confused of which type of laser you need, you can ask the customer service of Highlasers for help. Their professionalism and service experience will help you find a suitable laser product. Just enter into their official website www.highlasers.com and send them an email, they will give you a satisfied answer timely. 

3. Confirm what specification you need.

If you are acquainted with laser, you might know laser with different output power and wavelength, which you see, the color. Generally, low powered laser as 1mW- 50mW are workable for presentation, stargazing, entertainment places. High power laser with an output power more than 150mW can be applied for burning experiments. The special high power laser more than tens of kilowatts has practical applications in military battlefield and scientific research. For the details, you can also contact with Highlasers for answer that is more precise. Please note, when operate high power laser, it is necessary to have a protective measures, wearing a pair of laser safety goggles for instance.

  

I believe above three steps is necessary to read for one who is going to purchase a laser pointer. Any blind purchase might bring you hurt in both money and body aspects. To select a shoddy laser is not only a waste of money, but also an injury to human eyes. In addition, enough safety knowledge is especially necessary when people hold a high power laser in hands. Do be more careful before purchasing, and you can finally get the most satisfied laser pointer at last. Moreover, please do remember, Highlasers is always beside you in the laser road.

Scientists Make Hole on Drosophila's Head to Peek Into Brain Operation by Laser

Laser is geared to high technology, is rooted in people's daily life. Laser has a widely application, such as medical, military, industry, presentation and beauty. Recently, it is applied to biology. Scientist wants to know the brain activity of drosophila, he use laser instruments to make hole on its head, as the below picture shows. The only instrument to do the operation is a 3000mW laser pulse. The laser beam drills a 20 microns hole on drosophila's eyes, with depth of 250 microns. As showed in the yellow part of picture. The hole is tiny as a piece of hair. This research is also test on worm, ant and mouse. With the help of laser drilling, microscopic observation of animals allowed scientists to learn more features of animal biology. Seed a tiny lens into puny body of living mouse to observe and study how cancer formed and assess potential drug efficacy. It usually spends a long times to experiment with small animals and needs consummate skill and automaticity.

At present, Supriyo Sinha, IT specialist of Stanford University, developed a new way. It can do microscopic examination to animals in a very fast speed, less than s second time. There are three steps. First, scientist should anesthesia drosophila. Use tweezers clip insect careful and paste it on glass fiber to fix body and head. Then, use high power pulse ultraviolet laser punch at its head, the hole is about 12-350 microns. At last, put the armed drosophila into saline solution, this to make sure all the dissection process in a healthy environment.

Scientist analyzes drosophila with help of microscope. This tested drosophila is improved by genetic modification. Vivo protein combined with calcium ion release the green light, thus convenient for study the characteristics of brain nerve activity of fruit flies. According to reports, it will cost long time to observe brain activeness by traditional method, almost 18 hours. While the latest laser drilling technology needs only hundredth of the previous time. In addition, it can do more experiments on living animals at the same time. At present, the latest experimental results are published on Proceedings of the National Academy Sciences.

Laser technology is quite a help technology in the field of biology. With the help of such high precision technology, people can learn more information of the insects and in case to help human beings in solve of human disease. We can image that one day, the cancer can cure and people can clearly know what the animals are thinking and even communicate with them. Thanks the science.

A Shinning Green Beam I Met On My Way Home

It was a cold day and already dark. I just run my motor bike to home after a day work. It was such a cold day that makes me feel lonely and need person to chat to warm my heart. You may understand my feeling, an alone girl without boy friend to show a loving care for me, especially in such a cold day. Gosh, don't make myself fall into such emotion. Just call a friend and save myself. I call my best friend, Huffy. We are university schoolmates, live in one room. After graduate, she work in another county so we only contact by phone and mail, haven't seen for a long time, but she always comprehend me very much. We chat for a long time, ask about work, life and her exam that makes me feel better. Suddenly I saw a shining green beam lying in the sky. The light source is ahead of me in a long distance. I described to Huffy about it and she wondered about it. We just hold on the call and I riding to the beam. It is a laser pointer. To tell the truth, I haven't hear about it before. In our country, there are also lasers but they are low power in general and equipped on toy weapon. 

Therefore, it only releases weak beam or even no beam but a shining spot. It is my first time seeing a real laser pointer. I walked close to it and observed for a while, at the same time, I described it for Huffy. She said she has not seen such things before, either. The beam is brilliant and thin. There are also large amounts of finely ground particle among the beam. The holder told me that is the suspended particles in the air. He also introduced that if it were in a vacuum environment or just pure air, the beam will more pure. However, in an amateurish sight, the flaring particles make beam more beautiful.

Huffy was very considerate and told me just enjoy it. She is such a good girl and understands me very well. I do need time to see the laser earnest. The curiosities drive the chill away. I consulted to laser holder about the details. He was enthusiastic to explain for me. His name is Yale. I wondered how long this beam is. I just couldn't see the end of it, it already insert deep in the night sky. Yale explained for me in patience that his laser is a 50mW laser pointer, which is able to exposure to 2000m away in usually environment, and will longer in a clean environment. That is amazing, I just saw that it is hi-power even beat to star. Yale said it is because of endpoints and human limited vision. Moreover, he told me other things such as the color and wavelength. He collects all sorts of color laser pointers. At last, he invited me to play with him and other laser amateurs.

That was sweet and I do need concentrate on some new hobbies but not the boring mood.

Laser pointer is a magical thing that can make me happy. The light world makes my living world energetic.

This unexpected case makes my home way shorter and warmer. Thanks to Huffy and Yale.

Are Laser Pointers Illegal?

We can realize that laser is powerful through watching the laser experiments video from YouTube. With such a little body, its beam can burn the paper and even your skin. However, everyone wants one to make you powerful. Nerds and pet ladies also worried about the laser pointer in their hands, and questions:" Are laser pointers illegal?" That is unnecessary. Before you have that fear, you should answer firstly: Is your laser pointer powerful? The national institute, Food and Drug Administration, shows that the majority laser pointer circulates on the market is under 5mW and safe to use. The laser pointer play for pet and children and presentation is less than 5mW. So just, be assured use. That is from an official statement, but some laser amateur do a research and the study shows a majority of the tiny laser pointer on the market exceed the power level limits, in other word, the actual output power is greater than that of labeled power, 5mW. According to FDA, anything more powerful than 5mW are technically not belongs to laser pointer any more. Nevertheless, to factories and businesspersons, pure 5mWlaser pointer is harder to make, and will increase the cost to make the filtration system. That is why the nerds and pet women would have the worry about whether the laser is safe to use, whether the laser in their hands is pure 5mW. Adults should be much careful about using laser pointers, especially green laser pointer. That is reasonable. In the study, more than 90 percent of green laser pointers do not comply with FDA regulations, and red laser pointer is about 44 percent. Faced with such a chaotic laser market, laws in many states are explicitly stipulated that forbidden to sell or even give a laser pointer to anyone who is 18 years old and younger. Forbid to use a laser pointer in public. Shoot a laser pointer at police, firefighters, ambulance workers or other uniformed workers is not only a impolite behavior, but also absolutely not legal. In addition, will be fined, jailed or reports slate. President Obama signed a reform act of 2012, it says shining a laser beam at or in the flight path of aircraft is a federal crime. It will be punishable by up to $250,000 and five years in prison. That is all because of the unpredictable huge energy of laser pointer.

What kind of laser pointer is safe? Which shop sales reliable laser pointers? This is becoming a more meaningful question. To general usage, such as pets' toy, presentation or stargazing, 5mW is enough and must limit in the security 5mW scope. The online shop I would like to recommend here is www.highlasers.com . It is a professional and reliable laser devices supplier, supports all kinds of laser products, such as handheld laser, laser sight, laser alignment or OEM laser. It also accepts your large quantities of special customization. It is quite a good place for laser amateur. Also offer other varieties of power and wavelength.

The Accident Caused By Improper Use of Laser Pointer

Laser pointer is popular and continue sell on a large scale. But with seldom limitation of the laser sell, so kids are able to get one from the internet himself. But has rare knowledge about laser pointer, especially the laser safety, just be fascinated to shining laser beam. Hence, here comes the mischief of laser products by innocent kids. Just give you a example. Last year on April fool's day, police in St. Louis successful capture a reckless child. The guy named Justin Stouder is 24 years old and his crime is abuse of laser pointer. Justin use a green laser pointer to shoot to a helicopter cockpit in a high tower. He admitted that he do this just for fun. The suffered pilots described, his behavior just like splashing a whole bucket of green paint on his cockpit glass, and this caused his temporary blindness. Justin was in bad luck, the helicopter he shoot is a police helicopter! After the suffered pilot's visual acuity returned to normal, he assisted the police about his capture. The hurt pilot said that he don't think it's just a April fool's joke. According to federal law, such risk behavior which interfere with the flight, may be fined up to 20 years of imprisonment or a fine of $250000. I think Justin should thanks the god for without being punished severely by police. Justin apologized to public, he said he did not know before that laser pointer can caused such a serious consequences. He said he is blind to laser pointer, he usually use it for star gazing, and one day, he found the plain was shining on the sky, so with great curiosity, he shoot to plain. It is such a dangerous thing and acknowledged that " this is a very selfish mistake."

No matter how, Justin is lucky. David Taylor may not have such a good luck. As the BBC news reported, in March of this year, a British youth named David Taylor, was a suspect twice irradiation to use a laser pointer shoot into a helicopter cockpit in its home in the Camden. He was eventually sentenced to reformatory reformation training for three months.

The two cases I just show you is the uncomely use of laser pointer. Belong to laser safety. I will summarize the announcement about laser safety.

First, don't use laser pointer to shoot to the skin or eyes of human beings and animals.

Second, don't watch the laser beam with your naked eyes.

Third, put the laser pointer far away from your children, and when you don't use it, take battery out for safety case.

Forth, buy a FDA laser pointer from a professional online laser shop. In my opinion, www.highlasers,com is a good choice for you. For more information, you may visit www.highlasers.com now.
