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.

Custom Vertical Cavity Surface Emitting Laser 2 5G
Because VCSELs emit from the top surface of the chip, they can be tested on-wafer, before they are cleaved into individual devices. This reduces the cost of the devices. It also allows VCSELs to be built not only in one-dimensional, but also in two-dimensional arrays. The larger output aperture of VCSELs, compared to most edge-emitting lasers, produces a lower divergence angle of the output beam, and makes possible high coupling efficiency with optical fibers.
