Basic Principles of High Power IR Laser Diodes

High power IR laser diodes are semiconductor devices that emit infrared light through the process of stimulated emission. They are composed of a p-n junction, which is formed by doping a semiconductor material with impurities. When an electric current passes through the p-n junction, electrons and holes are generated, and they recombine to emit photons with a specific wavelength. The infrared light emitted by high power IR laser diodes is typically in the range of 700 nm to 3000 nm, which is suitable for various applications in different fields. The key factors affecting the performance of high power IR laser diodes include the material composition, structure design, and thermal management. The most commonly used materials for high power IR laser diodes are gallium arsenide (GaAs), aluminum gallium arsenide (AlGaAs), and indium gallium arsenide (InGaAs).
