摘要：
Earlier, computer simulation discovered the effect of catastrophic and asymmetric change in the efficiency of second harmonic generation by high-intensity femtosecond pulses under phase mismatch. Based on this effect, a simple method for experimentally verifying the existence of the frequency conversion bistable mode predicted earlier is proposed. The results of computer simulation are corroborated by analytical dependences obtained in the long-pulse approximation. (c) 2005 Pleiades Publishing, Inc.
