Technology of Ultraviolet Laser Diodes

UV laser diodes are based on the principle of stimulated emission of radiation, where an electron transitions from a higher energy level to a lower energy level, emitting a photon in the process. The key components of a UV laser diode include the active region, which consists of a semiconductor material with a direct bandgap, and the cladding layers that provide confinement of the emitted photons.

The active region is typically made of a compound semiconductor, such as gallium nitride (GaN) or aluminum nitride (AlN), which has a direct bandgap suitable for UV emission. The cladding layers are made of different semiconductor materials with varying bandgaps to ensure proper confinement of the photons. The structure of the UV laser diode is designed to maximize the extraction of the emitted photons, resulting in high efficiency and power output.
