A study of cooperative Raman scattering
Abstract
Cooperative Raman scattering at the Q01(1) line of molecular hydrogen is investigated experimentally and theoretically. It is found that in the case of coherent nonstationary excitation, Raman scattering pulses are characterized by a delay relative to the pumping pulse maximum, with the delay time being inversely proportional to the hydrogen pressure and the laser power density. The scattered radiation is also characterized by intensity pulsation. The effect of four-wave parametric interaction on cooperative scattering is analyzed. Experimental results are found to be in qualitative agreement with theory.
