摘要：
We introduce a model of degenerate four-wave mixing in saturable absorbers in the transient regime when the interacting pulses have a duration much shorter than the lifetime of the excited-state level. Our model takes into account of the depletion and the mutual interaction of the pump waves. We study the influence of excited-state absorption on phase conjugate reflectivity. This theory agrees with experimental investigations made in Cr4+:GSGG with nanosecond pulses at lambda0 = 1.06 mum. A reflectivity of 0.6% is achieved and imaging capabilities are demonstrated.
