Principles and Structure of the Diode Laser

A laser is device that emits light through a process of optical amplification based on the stimulated emission of photons.
Diode laser is electrically pumped, recombination of electrons and holes created by applied current introduces optical gain.

Laser Bar


Laser Stack


A diode stack contains a number of diode bars, which are arranged in the form of a stack.
Diode stacks can provide extremely high output powers of hundreds or thousands of watts to used for the pumping of high -power solid-state lasers, or used directly for material processing.
Due to the simple structure, the maintenance cost is lower than other lasers.
