Cat mutually pumped phase conjugation configuration is discovered and investigated by using two-wave mixing in (K_(y)Na_(1-y))_(2z)(Sr_(x)Ba_(1-x))_(1-z)Nb_(2)O_(6) (KNSBN) crystal. When only one signal or pumped beam does not give birth to phase conjugation, the maximum reflectivity of signal and pumped beam attain 140% and 30% due to two-wave mixing, respectively. The experimental results show that the two-wave mixing can reduce the threshold of incident beams power, extend the incident angle range, and shorten response rate in the process of self-pumped phase conjugator (SPPC) in KNSBN crystal.
