808nm diode laser manufacturers take you to understand the classification of diode lasers

808nm diode laser manufacturers take you to understand the classification of diode lasers

808nm diode laser manufacturers tell you that the P-N junction in a diode laser is formed by two layers of doped gallium arsenide. It has two flat-ended structures, mirrored parallel to one end (highly reflective surface) and one partially reflective.

808nm diode laser manufacturers tell you that a laser diode is essentially a semiconductor diode. According to whether the P-N junction materials are the same, laser diodes can be divided into homojunction, single heterojunction (SH), double heterojunction (DH) and quantum well. (QW) Laser Diode. Quantum well laser diodes have the advantages of low threshold current and high output power, and are the mainstream products used in the market. 808nm diode laser manufacturers tell you that as component materials, compound semiconductors such as AlGaAs, InGaAlP, InGaN, ZnO are used. Due to the poor transition probability of Si (probability of current conversion to light) used in LSI, Tr, Di, etc., it is not suitable for lasers. diode.
808nm diode laser manufacturers tell you that compared with lasers, laser diodes have the advantages of high efficiency, small size, and long life, but their output power is small (generally less than 2mW), poor linearity, and poor monochromaticity, making them suitable for wired applications. The application in the TV system is very limited and cannot transmit multi-channel, high-performance analog signals. In the return module of the bidirectional optical receiver, the quantum well laser diode is generally used as the light source for uplink emission. 808nm diode laser manufacturers tell you that when the laser diode injection current is below the critical current density, the light-emitting mechanism is mainly spontaneous emission, the spectral dispersion is wide, and the bandwidth is about 100 to 500 angstroms.
