【Abstract】 Cat mutually pumped phase conjugation configuration are discovered and investigated by using two wave mixing in KNSBN crystal. When only one signal or pumped beam does not give birth to phase conjugation, the maximum reflectivities of the signal and pumped beam are attained to be 140% and 30% due to two wave mixing, respectively. The results of experiment show that the two wave mixing effect can reduce the threshold of incident beam power, extend the incident angle range and shorten the response rate in the process of self pumped phase conjugator in the KNSBN crystal.更多还原
