500mW 850nm VCSEL Diode

Vertical Cavity Surface Emitting Laser (VCSEL) is a semiconductor laser whose laser emission direction is perpendicular to the P-N junction plane and whose resonant cavity plane is parallel to the P-N junction plane. It is a type of surface emitting laser. The light of EEL edge emitting laser is emitted horizontally from the edge of the chip. Compared with EEL, VCSEL has a more economical production process and a faster response, so it has replaced traditional edge emitting lasers in more and more applications.
