Compression of 40-ps Nd:YAG laser second-harmonic pulses in water using backward stimulated Raman scattering (BSRS) is studied for the first time. The first Stokes component pulses (wavelength ≈650 nm) compressed by a factor of ~30 to a duration of 1.3 ps and peak power of 4 MW are obtained. Physical effects limiting generation of subpicosecond pulses in water under BSRS are discussed.
