摘要： The nondegenerate four-wave mixing in a linear self-pumped phase-conjugate mirror with arbitrary-chosen complex coupling constants has been studied by numerical methods. The frequency detuning and the phase-conjugate reflectivity versus cavity path length detuning for different complex coupling constants are discussed in detail. It is found that multigrating operation in some cases can enlarge the interval of cavity path length detuning to be compensated for by frequency detuning and improve the phase-conjugate beam generation. The phase relation between the output phase-conjugate beam and the input beam is calculated and the result is in agreement with the experimental results.
