This paper describes what is thought to be the first generation of a continuous wave deep ultraviolet laser at 275 nm by efficient frequency doubling of a blue-diode-pumped Pr:YLF laser at 550 nm. A TEM00 mode deep UV laser radiation at 275 nm with an output power of 351 mW was obtained through the use of novel methods of coating and LD collimating. The authors could not find any prior reports on a Pr:YLF laser operating at 275 nm and believe this paper is the first.
