What is it about?
The performance of laser diodes working below 350 nm (ultraviolet wavelength regime) can be drastically improved by nonpolar crystal planes. Light sources at around 265 - 280 nm are suitable for sterilization and water purification. The light emitting material is AlGaN alloy semiconductor.
