Parameters of the optical parametric amplifier (OPA), based on two BBO crystals were studied. The OPA was made with the schematic of the extraordinary wave walk off compensation. Efficient amplification of the weak signal (λ = 1053 nm) in the field of the strong pumping wave (λ = 532 nm) was obtained. The measured value of the amplification was equal to ~10 6 . The noise level of the parametric amplifier was less than 10 −3 from the signal level.
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.
