Power of Laser Pointer

With the development of technology, laser pointer has became one of the latest technical products, laser pointer finally applied in our daily life, while laser has been existed for almost 60 years. Laser is a mysterious stuff that seldom has people has a well knowledge about it, even though you own a laser pointer. So what is laser pointer? As per the Wikipedia, laser is defined as "light amplification by stimulated emission of radiation." And in modern level of science and technology, the stimulation is accomplished by diode. Diode is an integral part of laser pointer. Then what is the special light used for? Well, laser is used for a variety purposes according to its almighty nature. The purposes including pointing out aim in a presentation, museum interpretation, sales house sand table indicating, aligning materials at construction sites, guided tools. Play with pets at home. For doctors, it is used for cosmetic and surgical procedures. For workers, it is used for carve up and alignment. Laser is also being able to use in the hunting, hiking, shooting and the beauty fields. Many items you encounter on a daily basis use laser, including CD and DVD players, bar code scanner dental drills.

After a preliminary understanding of laser, it will have many help in the next introduction of laser pointer. Laser pointer is a small handheld portable device with a power source and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. (Wikipedia) Laser is divided according to its output power and wavelength. The output power is stated in type of milliwatt. Lasers are divided into different safety classes on basis of output power. The technical of output power as it relates to laser products is the power level of the laser beam. A higher output power is brighter than a lower output power. So does the cost. More powerful laser cost more. 

Thus far, laser pointer has the different output power from 1mW to 3000mW. According to FDA, only the laser pointer with output power 5mW below meet with the safety standards and available for market. But it doesn't mean that it is forbidden to produce or to own a laser pointer more than 5mW, that is quite a ridiculous idea. What the FDA means is to let users to pay attention to the safety operation. More than 5mW laser pointer will lead the unimaginable damage. 50mW is able to burn cigarette or wear out the balloon in a flash. Even not to mention your eye. But we truly need more than 5mW laser pointer. Take stargazing for example, 5mW laser pointer is difficult to clearly indicate. The higher the power, the bigger the energy. The high power laser pointer even be able to cut board and glass pane.

So is there an all-in-one solution? Maybe a pair of laser safety goggles can be easily solve our scruple. Wearing laser safety goggles can protect eyes. But at the same time, it is also need to pay special attention that don't shoot laser on the glaze with reflection ability, and human body especially. Power of laser is the most important reason that laser can be popular and can't be replaced.

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.
