Description

The possibility of induced backscattering parametric decay instability resonant suppression by harmonic pump-frequency modulation is demonstrated experimentally. It is shown that the pump anomalous reflection is strongly reduced at the modulation frequency equal to the difference of the decay instability eigenfrequencies. The parametric instability feedback control method is proposed based on this effect
