Introduction to Low Power IR Laser Technology

Low power IR lasers, also referred to as infrared diode lasers, are solid-state devices that emit light in the infrared spectrum. The term “low power” signifies that these lasers produce an output of less than 5 mW, which is significantly lower than the power output of high power IR lasers. The key characteristics of low power IR lasers include their compact size, high efficiency, and the ability to operate at room temperature.

How Low Power IR Lasers Work

The working principle of low power IR lasers is based on the stimulated emission of photons. When a diode is forward biased, electrons move from the conduction band to the valence band, releasing energy in the form of photons. These photons are then amplified through a process called optical gain, resulting in the emission of a coherent infrared beam. The diode laser structure typically consists of a p-n junction, a cladding layer, and an active region where the optical gain occurs.
