Abstract:We report for the first time coherent ultraviolet radiation at 284 nm by intracavity sum-frequency generation of a 607 nm Pr:YLF laser and a 532 nm frequency doubling Nd:YVO 4 laser. The ultraviolet laser is obtained by using double resonator, type-I critical phase matching CsLiB 6 O 10 (CLBO) crystal sum-frequency mixing. With a total pump power of 18.8 W (3.1 W pump power for the 607 nm Pr:YLF laser and 15.7 W pump power for the 532 nm Nd:YVO 4 frequency doubling laser), a TEM 00 mode ultraviolet laser beam … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
