THE EFFECT OF THE STOCHASTIC PROPERTY OF LASER ON THE DEGENERATE FOUR-WAVE MIXING
激光场的随机性对简并四波混频的影响

The effect of the stochastic field on the degenerate four-wave mixing signal intensity hag been studied basing on the phase-diffusion model. It is shown that the ratio of the correlation time of the laser source to the relaxation time of the induced grating plays an important role. The effect of the stochastic property of laser source on the linewidth of mixing signal has also been discussed.
