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
~10 ps using a mismatched grating-pair. The spectral characteristic of the Raman pulse is calculated and the results
explain the observed transient features.
