Development Of Semiconductor Material As A Working Laser Pointer
A semiconductor laser is a laser pointer developed in the 1960s. Semiconductor materials are used as working substances. Since the late 1970s. Semiconductor lasers are clearly moving in two directions. One type is information lasers for the purpose of transmitting information. The other type is a power laser that is designed to directly use the optical power of the output laser.

Application
The working principle of the semiconductor laser pointer is to use the excitation method of injected current. The electric energy injected into the current is used to realize electro-optical conversion through the semiconductor material. Output laser. Semiconductor lasers can be used as pump sources for fiber lasers and solid-state lasers. It can also be used to make direct semiconductor lasers. Used as light source in materials processing, laser medical, lidar and other fields.
