“…There are several approaches to obtain UV lasers, the most broadly applied methods is to use nonlinear crystal frequency tripling Nd 3+ :YAG lasers in the cavity. However, this method requires two frequency transformations, signi cantly reduces the conversion e ciency of the laser and increases the complexity of the structure [7][8][9].…”

We demonstrated a continuous-wave (CW) ultraviolet laser (UV) at 360 nm generated by intracavity frequency doubling of Pr:YLF laser at 720 nm. It was more compact and simpler than the reported UV laser, because a straight cavity was adopted. The entire length of the laser is 75 mm, and the resonant cavity length is only 25 mm. By using an InGaN laser diode (LD) emitting at 444 nm with a maximum incident power of 3.1W, we achieved the CW UV laser with an output power of 252 mW. The optical to optical conversion efficiency was up to 8.1%, and the output power stability was better than 2% in 2 hours. It can be applied in spectral analysis, material analysis, bioengineering, optoelectronic detection, medical treatment, etc.

Since the discovery of the frequency doubling phenomenon in the 1960s, there has been a continuous emergence of solid-state lasers with varying wavelengths. Technological advancements have facilitated the generation of various types of ultraviolet lasers by employing diverse frequency doubling crystals and pump sources. Ultraviolet lasers find widespread applications in processing, microelectronics, grating fabrication, and beyond. This article presents a comparative analysis of the strengths and weaknesses of different ultraviolet lasers, explores solid-state ultraviolet lasers of varying wavelengths achieved through frequency doubling, and delineates their diverse applications.
