Laser Overflow

Laser are used as weapon in many films. Usually in the blighted earth films. And the audience are quite shocked by its power. The gun or rocket are not the unique weapon to show the power, laser are identified as the high-tech weapon with many advantages that the gun doesn't have. Such as the hi-power, portability, easy to operate, and well-adapted. It is precisely because of these, laser are forbidden for people to hold as weapon such as the gun do. Only the low powered laser is popular. Well, have you ever image that if the laser is popular used, what the world will be.

Ok, let's make this picture.

The fire is replaced by laser. In few second, the food is finished, just as what happened in the big bang theory, the scientists are use laser to heat food.

That is about the good sides. But what about the harm. Imagine that the laser are used to destroy the earth. The terrorists' eyes are equipped with laser, their eyes stare there, where will be destroyed. Like the monster in computer game. The two beam can destroy a building. 

 

The bank robber and the carnapper can steal the goods easily, just take out their laser pointer from pocket and use it to cut the glass, without a trace.

Wow, the world must be in a mess, and it is quite wise for the government ban the importation of high-intensity laser pointers. Well, every coin has two sides, just like the chinese sayings: the small wager chief use for delight bet that killed the cat. So laser have its harm side but also with good side. The right use of laser is legal and reasonable.

Buy laser from legal online store is a wise choice.  

Use Laser to Play a Game

The games such as Plants vs Zombies or Angry Bird in our phone may be a little boring, even the  massive online games. Have you ever think about playing a real game in reality. of course not Rock Paper Scissors. Well, let me guide you. The Big Bang Theory! It is quite a funny  teleplay but the most happy thing for me is the game played inside. As a big fan, I followed almost every game that appeared. Today I will introduce you a best enjoyable game.

The tool you need is some small piece of mirror, a laser pointer, and a alarm apparatus. And if your laser is without color, a bottle of depurative is also needed, such as what Sheldon do in the teleplay.

Well, everything has been done, let's stat our game.

First, Fixed on the wall around the different angle mirror.

Then, turn on your laser pointer and shoot to one mirror, and adjust the angle to make every mirror can  refract the laser. Though the refraction, it will form a coherent laser route.

Last is install a alarm apparatus at the end of line. The line will be interdict once a player encounter the laser, meanwhile the alarm will make a sound as it can't get the laser signal. Are you clear？ ok , everything had been done, let's play!

 For the first time I was play with my friends Anthony and Michael and my girlfriend Holiday, an interesting name, right?

 As the game designer, I do demonstration for them first. There has seven times refraction. Well, although it is designed by myself, it is quite hard for me to finish it. I just past the half of the game. So embarrassed, they three have a lot of fun in watching. Michael is the second to play, he is slim and confident to be able to complete it. Right, he is quite thinner than me, but he has a stiff limbs. I don't think he will succeed. Well, Well, Well, let's see what happened. He fall over his own feet. Just passed three line. What a poor Mike. Then Anthony want to have a try. I bet he will win, because he likes dancing. I think he can handle it easily. And finally he do finish it. Last player is my girlfriend, Holiday. She is a enthusiastic person and enjoys playing game very much. This is the most important reason why I make this game. Hope she will like it. But the game looks easier but harder to do. She tries four times and the best grade is nine lines, better than me. *O*

That is just a game from The Big Bang Theory. Sounds interesting, right? Just a laser pointer and a alarm apparatus and some mirrors. The alarm apparatus was home-made, and the laser pointer is bought from internet, www.highlasers.com, hope it can help you,too.

Fun from game, fun in life.

Laser Pointer for Meteor Shower

There are many amateur astronomers in the word and in December they might be crazy because of Geminid Meteor Shower. It is the biggest one of the following half year. The geminids move slowly. It can be seen in December and usually peak around the morning of 14th. The shower will be 120-160 meteors per hour under optimal conditions. Can you imagine how much fun it will be to watch a meteor shower.

Amateur astronomers usually use the telescopes and also equip a green laser pointer to point star or other heavenly bodies because the visible beam of green lasers can reach far into the atmosphere so that you can point at stars, constellation and galaxies exactly. The best part is everyone around you can see exactly what you are pointing to through the green beam. Other amateur astronomers may jealous of your easiness while they are point with their fingers painstakingly.

Then what kind of lasers are suitable for pointing star？The first point is choosing the color. The wavelength decide the color. The 532nm green laser is more suitable because it is the lightest color among the others. Next one is power. The power from 5mw to 150mw is enough. Which one you choose is depend on the weather and purpose. 5mw power is ok in starry sky and 150mw is needed when it is cloudy. On the other hand is your purpose. If your single use is pointing star then a 5mw laser is ok. Anything less would not have enough power to be seen far enough. 5mw is low powered and safe. And you can also use it to play with your pet, but forbidden to shoot to people or animals. While if you want to use it to burn paper, cigarette, fur or something else, then maybe you should choose the high powered laser and it can also be used to point star. At the same time you also need a pair of laser safety goggle.

What's more, it is easy to operation, with one button to switch on-off. For children, we have safe key.

Equip your telescope with a 532nm green laser pointer and star your fantasy astronomical travel.

Laser Warning Device

Laser device with warning function are widespread used because of its advantage. There are many scenes like these in the 007 system movies: make a beam of light fill up the monitoring area, when someone enter the area, he will block the light and then the laser alarm device will send out a particular signal which will attract the attention of guardians in order to take appropriate measures.

Compared with the device with visible laser beam, semiconductor laser unit with many advantages which as listed:

It launch the infrared light which is invisible for human eyes.

Launch in pulse type, can be encoded and make the false signal failure.

With high efficiency, can produce high power and that will prolong the useful time and distance.

Good directionality. It is able to reflect by prism. This can make the laser beam as an invisible wall around a certain area, and block the inward or outward.

When the light are kept out, the laser warning device will ring. The experienced user can judge from a variety of different information of the target category.

This kind of device can be applied to the airport, warehouses, and other secret facilities in barracks, to help the guards to work.
