Characteristics of generation of a picosecond continuum in a noncentrosymmetric medium

An investigation was made of the laws governing the conversion of a single pulse of 9488 cm^–1 frequency and 6 psec duration into visible radiation in the continuum range, which took place in basically different media, one of which was isotropic (D₂O) and the other noncentrosymmetric (KDP crystal). The continuum formed in KDP was due to the combined influence of stimulated Raman scattering and parametric interaction.
