A high efficiency Nd:GdVO 4 bounce laser in band pumped at 879 nm is demonstrated for the first time. From a side pumped Nd:GdVO 4 crystal, 8.2 W output was obtained with 18.5 W absorbed pump power. Corresponding slope efficiency with respect to the absorbed pump power was 51.4%, and the beam quality factor M 2 is 1.13 and 1.15 for tangential direction and sagittal direction, respectively. Effects of crystal's dop ing concentration and temperature on laser power and conversion efficiency were also investigated.
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.
