Stimulated Raman scattering in the visible with a multipass cell

摘要: In experimental studies of stimulated Raman scattering in a multipass cell (MPC) with frequency-doubled single-mode Nd:YAG laser at 532 nm, it is found that only forward Stokes generation observed and the growth saturation beam are agreement simple plane wave, transient theory scaled to account for focusing, multiple passes. The absence second generation, backward anti-Stoke discussed terms low gain per pass MPC. It concluded MPC provides an ideal system studying visible lasers without four-wave processes usually seen single-focus geometry. >
