Ultrafast electronic dynamics during femtosecond laser-induced damage in omnidirectional reflector
飞秒激光作用下全向高反膜破坏的激发过程

The use of optical frequency domain phase conjugation (FDPC) to suppress pulse impairments due to cross-phase modulation (XPM) in optical fiber systems is propo sed. Evolution of Gaussian pulses in the system using midway FDPC is analyzed thoretically and simulated numerically. It is found that pulse waveform impairmen ts induced by XPM can be suppressed effectively by FDPC. The impairments due to group-velocity dispersion and self-phase modulation can be suppressed simultaneously. Suitable initial time delay and pulse chirp of pulses can improve the suppression and compensation for the distortion.
