The Powerful Green Laser Pointer
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).
