Introduction to High Power Laser Diode Module

A high power laser diode module is a device that converts electrical energy into laser energy through the optical properties of a laser diode. It is composed of a laser diode, a collimating lens, a focusing lens, a heat sink, and other components. The laser diode is the core component of the module, which emits laser light through the process of stimulated emission. The collimating lens and focusing lens are used to adjust the beam quality and focus the laser beam. The heat sink is used to dissipate the heat generated by the laser diode during operation.

Working Principle of High Power Laser Diode Module

The working principle of a high power laser diode module is based on the optical properties of the laser diode. When the laser diode is forward biased, electrons and holes are injected into the active region. Under the action of the electric field, electrons and holes recombine, releasing energy in the form of photons. These photons are then amplified through the process of stimulated emission, forming a laser beam. The collimating lens and focusing lens are used to adjust the beam quality and focus the laser beam.
