A new technique for suppressing of stimulated Raman scattering in plasma of the laser fusion: fast frequency modulation of the pumping radiation

摘要

A new technique based on the fast frequency modulation of the laser radiation is proposed for suppression of stimulated Raman scattering in plasma in conditions of the laser fusion. It is shown that Raman gain for the backward SRS can be reduced twice providing rate of the saw-toothed form frequency modulation as high as 2% per picosecond.
