Research on chirped pulse stimulated Raman scattering in ethanol

We report a generation of 10.6% conversion efficiency near 1053 nm first order Stokes pulse in stimulated Raman scattering pumped using 800 nm Ti: sapphire based femtosecond pulses that are stretched to 460 ps, obtained by use of a single pass ethonal Raman shifter. The Stokes pulse almost maintains the bandwidth of the pump and is compressed to similar to 10 ps using a mismatched grating-pair. The spectral characteristic of the Raman pulse is calculated and the results explain the observed transient features
