Abstract
An efficient yellow-orange laser radiation source was produced by the stimulated Raman scattering (SRS) of barium nitrate (Ba(NO3)2) crystal. With a 532 nm laser as the exciting source, the Stokes conversion efficiency is up to 68.3 %. Under a pump energy of 119.8 mJ, a maximum output energy of 40.9 mJ at 563 nm and 28.5 mJ at 599 nm were obtained. By further second-order nonlinear optical (NLO) frequency conversions, four ultraviolet (UV) laser wavelengths at 274 nm, 282 nm, 291 nm, and 300 nm were achieved. These new laser sources have potential applications in many fields, like bioimaging, medical diagnostics, and spectral analysis.
