Abstract

Transient stimulated Raman scattering (SRS) of 0.3 ps 515 nm laser pulses in ${\rm BaWO_4}$ crystal was experimentally demonstrated with efficiency up to ${\sim}{20}\% $ for the Stokes component with a wavenumber of ${\sim}{925}\;{{\rm cm}^{ - 1}}$ in a simple single-pass geometry. This anomalous high efficiency was obtained due to the laser pulse self-phase modulation resulting in spectral broadening and seeding the SRS. The applicability of seed pulse production for a high-pressure sub-picosecond ${{\rm CO}_2}$ laser amplifier via difference frequency generation in ${{\rm LiGaS}_2}$ crystal was numerically verified.
