Introduction to Infrared Laser Diode Module

What is an Infrared Laser Diode Module?

An infrared laser diode module, also known as an infrared laser diode module, is a device that uses a laser diode to generate infrared light. It is widely used in various fields such as industrial, medical, scientific research, and communication. In this article, we will introduce the basic concept, working principle, application, and development trend of infrared laser diode modules.

Working Principle of Infrared Laser Diode Module

The working principle of an infrared laser diode module is based on the principle of stimulated emission. When a forward bias voltage is applied to the laser diode, electrons and holes are injected into the active region of the diode. Under the action of electric field, electrons and holes recombine and emit photons. The photons emitted in the same direction and frequency form a laser beam. The infrared laser diode module typically includes a laser diode, lens, and housing.
