How Infrared Laser Diode Module Works

An infrared laser diode module consists of a laser diode, a collimating lens, and a housing. The laser diode emits light through a process called stimulated emission, which occurs when electrons transition from a higher energy level to a lower energy level, releasing energy in the form of photons. The collimating lens focuses the emitted light into a narrow beam, and the housing protects the internal components. The key components of an infrared laser diode module are: 1. Laser Diode: The laser diode is the heart of the module. It emits light at a specific wavelength, which is determined by the semiconductor material used in its construction. Common materials include gallium arsenide (GaAs), gallium nitride (GaN), and indium gallium arsenide phosphide (InGaAsP). 2. Collimating Lens: The collimating lens focuses the emitted light into a narrow beam, ensuring that the laser diode operates efficiently and effectively. 3. Housing: The housing protects the internal components from environmental factors, such as dust, moisture, and temperature fluctuations.
