Observation of the picosecond supercontinuum

Properties of the picosecond supercontinuum generated from water have been studied. We have shown development of a stimulated Raman scattering cross-phase modulation spectrum at the anti-Stokes side of the pump frequency. Supercontinuum diffraction patterns have been recorded and diffraction angles for several wavelengths have been measured. Requirement of the supercontinuum generation power threshold have been found out for different outputs. We have also analyzed defocusing interaction among pulses of the pump train.
