Deep ultraviolet solid-state laser refers to solid state laser with its wavelength less than 230 nm, which belongs to the invisible light and its photon energy is large. Solid-state deep ultraviolet la-ser has wide application in optical emission spectrum, Raman spectrum, micro-processing for its small volume, line width, and high reliability. Deep ultraviolet laser output can be acquired by sum frequency or second harmonic generation. Compared to multiple harmonic conversion, though sum frequency technology has harsh application conditions due to its complexity and poor stability, it can produce shorter deep ultraviolet laser. It is an effective way to develop an all-solid-state deep ultraviolet laser source to multiple harmonic conversion though nonlinear crystals, but it is limited by the transmittance and phase matching conditions of nonlinear crystals in the deep ultraviolet region. In this paper, we have reviewed the development history, research status and application fields of deep ultraviolet all solid-state laser sources. In addition, the technical background and development trend of gain medium, frequency-doubling crystal and deep ultraviolet laser are summarized as well. Finally, the key technologies of solid state deep ultraviolet laser at home and abroad are discussed, which provides a reference for the research of ultraviolet laser. %K 激光,紫外激光,深紫外激光,全固态激光器,增益介质,非线性晶体
