Introduction to UV Laser Diodes
UV laser diodes are semiconductor devices that emit light at ultraviolet wavelengths, typically between 10 nm and 400 nm. They are a subset of laser diodes, which are known for their compact size, low power consumption, and ability to produce a highly focused beam. High-power UV laser diodes, in particular, are capable of delivering output powers in the kilowatt range, making them suitable for demanding applications.
How UV Laser Diodes Work
The operation of a UV laser diode is based on the principles of quantum mechanics. When a current is applied to the diode, electrons are excited and move to higher energy levels. As these electrons return to their original state, they release energy in the form of photons. In a laser diode, these photons are amplified and directed through a resonant cavity, resulting in the emission of a coherent, focused beam of light.
