Stimulated Raman scattering in crystals pumped by phase-modulated picosecond pulses

Stimulated Raman scattering in crystals pumped by phase-modulated picosecond pulses

The appearance of hysteresis in the dependence of the efficiency of transient SRS on the energy of picosecond laser excitation is studied. The hysteresis appears due to the frequency-phase modulation of laser radiation which changes the SRS gain with changing the degree of modulation. (nonlinear opt...

Zusammenfassung:The appearance of hysteresis in the dependence of the efficiency of transient SRS on the energy of picosecond laser excitation is studied. The hysteresis appears due to the frequency-phase modulation of laser radiation which changes the SRS gain with changing the degree of modulation. (nonlinear optical phenomena)
