Laser Diodes Explained: From Light Source to Everyday Tech
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.

Laser Diode
Below the threshold limit, the laser diode does not emit light but only due to spontaneous emission. As it exceeds the threshold, stimulated emission starts, and the optical power increases exponentially

Laser diode
Unlike a regular diode, the goal for a laser diode is to recombine all carriers in the I region, and produce light. Thus, laser diodes are fabricated using direct band-gap semiconductors.
