Abstract

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