Abstract When two beams of incoherent cw mode-locked ps laser pulses were incident upon opposite faces perpendicular to the a-axis of a Cu-doped KNSBN crystal, no mutually pumped phase conjugation as that generated by continuous waves was observed, however, the stronger laser beam generated its self-pumped phase conjugation which was weakened by the weaker one. When the intensities of the two beams were equal, self-pumped phase conjugation was completely quenched.
