Introduction to High Power IR Laser Diode

A high power IR laser diode is a semiconductor laser diode that emits infrared light in the range of 780 nm to 3200 nm. It is widely used in industrial, medical, scientific, and consumer applications due to its compact size, high efficiency, and long lifespan. The power output of high power IR laser diodes can range from a few watts to tens of watts, making them suitable for various applications requiring high power.

Working Principle of High Power IR Laser Diode

The working principle of a high power IR laser diode is based on the stimulated emission of photons by electrons transitioning between energy levels in a semiconductor material. The semiconductor material used in high power IR laser diodes is typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). The key components of a high power IR laser diode include the active region, the p-n junction, and the metal contacts. When a forward bias voltage is applied to the p-n junction, electrons and holes are injected into the active region. As the electrons and holes recombine, photons are emitted. These photons are then amplified through the stimulated emission process, resulting in the formation of a laser beam. The wavelength, power, and polarization of the laser beam can be controlled by adjusting the composition and structure of the semiconductor material.
