What is the working principle of a diode laser module
Diode lasers work by stimulating the emission of photons at a semiconductor junction. The semiconductor material has specific energy band gaps that trigger the generation and amplification of coherent light. They consist of a p-n semiconductor junction, with a forward bias voltage applied. A Laser Diode is a semiconductor device similar to a light-emitting diode (LED). It uses p-n junction to emit coherent light in which all the waves are at the same frequency and phase. Their ability to deliver controlled energy in a tiny footprint has made. A diode laser is small enough to sit on your fingertip, yet fast enough to modulate at gigabits per second and powerful enough (in industrial versions) to weld metal.
