Visible to infrared semiconductor lasers have seen increasing applications in important areas such as display, lighting, data storage, telecommunication, sensing, and manufacturing due to compact size, excellent reliability, and power efficiency. However, UV semiconductor lasers still have much inferior performance compared to the solid-state and gas lasers due to different challenges including material quality, doping efficiency, carrier injection efficiency, and index reduction. This chapter reviews the cutting-edge development of the UV lasers including UVA, UVB, and UVC spectra to provide overview of this critical device technology.
