Abstract: The efficiency of stimulated scattering of laser radiation in heptane is studied. The reasons for the shortening of a reflected pulse and a decrease in the reflection coefficient with increasing the spectral width of pump radiation are analysed. A mechanism of photodissociation of molecules in a nonlinear medium is proposed that explains the reduction in the efficiency of stimulated scattering.
