Working Principle:

DM200-01-1-9560-1-LC uses a semiconductor laser diode, which is a metal–semiconductor device formed by depositing an N-type gallium arsenide layer on top of a p-type gallium arsenide layer. The electron-hole pairs generated when the diode is forward-biased will be concentrated in the P-N junction, which will then recombine and release energy in the form of photons. This process makes up the laser.

This process is always taking place in a semiconductor laser diode, which is usually an uncoated device. The power of the emitted light depends on the current and the reflective quality of the device. When light reflects back into the diode, the light intensity is amplified and the laser output power increases. This feedback mechanism is also called "resonator" or "optical cavity". This laser diode can achieve ultra-long-distance transmission, high-speed transmission, wide range of applications, high brightness and other advantages.
