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.

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.
