Technically, the เลเซอร์ light is enhanced by stimulated emission of radiation. Within each เลเซอร์ pointing device are small chips that are used to create radiation when an electric current through it. They are called ไดโอด เลเซอร์ the เลเซอร์. ในปัจจุบัน, several colors are emitted by a device known as เลเซอร์ pointers and practice for those products on the market. The colors of each device are achieved, according to the alignment of เลเซอร์ diodes in it a certain frequency of light measured in nanometers (นาโนเมตร).

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

สีเขียวที่ เลเซอร์ light has a powerful need to buy a unit with a capacity of 5 MW to 100mW! But beware, because with that power, the เลเซอร์ 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.
