Working Principle of UV Laser Diode High Power

The working principle of high-power UV laser diodes is based on the stimulated emission of electrons in a semiconductor material. When a forward bias voltage is applied to the p-n junction of the semiconductor material, electrons and holes are generated. These electrons and holes are injected into the active region of the laser diode, where they collide and recombine, releasing energy in the form of photons. The photons with the same energy and phase are amplified and emitted from the laser diode. The wavelength of UV laser diodes is generally between 200nm and 400nm, which can be used for various applications in the UV range.
