摘要：

This paper reports on self-pumped photorefractive phase conjugation using repetitively pulsed high intensity (MW cm(-2)) pulses of nanosecond duration. An intensity-dependent phase conjugate reflectivity is measured experimentally. In the corner self-pumped geometry the direction of beam fanning and corner self-pumping is observed to reverse above a critical intensity. Formation of a higher order spatial mode is reported for the external loop self-pumped geometry.
