Description
technical field [0001] The invention relates to the technical field of ultraviolet laser devices, in particular to a semiconductor diode-pumped ultraviolet laser. Background technique [0002] Ultraviolet laser is a kind of laser that generates ultraviolet beams. Ultraviolet lasers are divided into solid-state ultraviolet lasers (fiber optic ultraviolet lasers), gas ultraviolet lasers, and semiconductor ultraviolet lasers from the structure. Ultraviolet lasers have short output wavelengths, concentrated energy, and high resolution. The focus point can be as small as several microns, and they have broad application prospects in the fields of micromachining of precision materials, ultraviolet curing, and photolithography. In particular, semiconductor diode-pumped ultraviolet lasers have many advantages such as good beam quality, good power stability, high reliability, convenient use, and small size. The semiconductor diode-pumped ultraviolet laser tube adopts intracavity freq...
