Four sets of multireflection orders from cat self-pumped phase conjugators of Cu-doped (K0.5Na0.5)0.2 (Sr0.75Ba0.25)0.9Nb2O6 (Cu:KNSBN) crystals are reported for the first time to our knowledge. The novel phenomenon of transient pulsation of the multireflection orders is observed and analyzed. The nonconjugate part accompanying the returning phase-conjugate beam is observed in the cat self-pumped phase conjugators of Cu:KNSBN and is analyzed by multireflections and two-wave mixing.
