Technology of Low Power IR Lasers

The technology behind low power IR lasers involves the generation, amplification, and emission of infrared light. Here are the key components and processes involved:

1. Laser Medium: The laser medium is the material that emits light through stimulated emission. For low power IR lasers, the laser medium can be a solid, liquid, or gas. Common materials include gallium arsenide (GaAs), indium phosphide (InP), and hydrogen fluoride (HF).

2. Cavity Design: The laser cavity is a resonant structure that confines the light and enhances the stimulated emission process. It consists of two mirrors, one of which is partially transmissive to allow the output of light. The cavity design affects the laser’s output characteristics, such as wavelength, power, and coherence.

3. Pump Source: The pump source provides energy to the laser medium, promoting the stimulated emission process. Common pump sources include electrical, optical, and thermal methods. For low power IR lasers, electrical pumping is the most common method.

4. Cooling System: Since low power IR lasers generate heat during operation, a cooling system is required to maintain the device’s performance. This can be achieved through air cooling, water cooling, or thermoelectric cooling.
