Technically, the 激光 light is enhanced by stimulated emission of radiation. Within each 激光 指点设备时，通过它的电流小的芯片，用于创建辐射. 他们被称为 二极管 激光 the 激光. Currently, several colors are emitted by a device known as 激光 pointers and practice for those products on the market. 实现每个设备的颜色, 根据对齐 激光 在纳米测量它一定频率的光二极管 (纳米).

The color of the lights that are now available for sale are in red (671 nm), yellow (593 nm), green (532 nm), blue (473 nm) and violet (405 nm). With so many colors to choose from, can not prevent a color becomes larger among others. In this case, the green 激光 pointer has the highest sales per brand.The green 激光 pointer has a wavelength that is not too large, as infrared and not too thin, like ultraviolet rays. This gives the green light 激光 is ideal for any dark lighting. The light green is so vivid that the bar looks like a green bar above the solid powder.

The green 激光 light has a powerful need to buy a unit with a capacity of 5 MW to 100mW! But beware, because with that power, the 激光 burns the paper, pop balloons, and a little 'meeting. This can be dangerous if the wrong item, you should be responsible when you have this type of gadget device.This the green light is powerful enough that it is used by people in many fields such as astronomy, military, research and operations , and more.
