Russian Ultraviolet Laser Diode

Russian ultraviolet laser diodes are produced by specialized companies like ATC-SD, offering high-power, deep-UV devices suitable for scientific, industrial, and medical applications.

Manufacturers and Availability

In Russia, ATC-"Semiconductor Devices" (ATC-SD) is a leading company in the design and production of high-power laser diodes, including ultraviolet (UV) laser diodes, arrays, and modules. Their products are used in applications such as solid-state laser pumping, spectroscopy, material processing, medical devices, and space communications. Russian laser diodes are also listed on platforms like GoPhotonics, which catalogues multiple laser diode models from Russian manufacturers, though most commercially listed diodes are in the infrared and near-infrared range.

Technical Characteristics

Ultraviolet laser diodes typically operate in the 200–400 nm wavelength range, providing high spatial resolution and diffraction-limited performance.

Russian U

V diodes, particularly those based on AlGaN (aluminum gallium nitride), are designed for deep-UV applications, often in the 269–280 nm range. These devices are optimized for low lasing thresholds, high optical confinement, and efficient carrier injection. Recent research demonstrates that AlGaN-based deep-UV laser diodes can achieve significant performance improvements using a two-stepped Si-doped lower waveguide, which reduces the lasing threshold current and operating voltage compared to traditional designs.

For example, a proposed device achieved a lasing threshold current as low as 0. 002 A and a voltage of 4. 24 V, compared to 0.

4 A and 13. 8 V in conventional devices. These enhancements improve optical confinement, reduce electron leakage, and increase hole injection efficiency, making them suitable for high-precision applications.
