摘　　要：利用非简并四波混频体系制备出稳定的双模压缩光场,研究了压缩随时间的演化情况.同时,得到双模光场的主方程.经分析可知,在满足一定的条件下,能够制备出稳定的双模压缩光场,并且双模光场的压缩程度与双光子泵浦光强度、合作参量、失谐频率有关.We apply nondegenerate four-wave mixing processes to the generation of squeezed light and study the evolution of squeezed light with time. We get the .master equation of the two-mode field. We also show that the two-mode cavity field exhibits stable squeezing under some conditions. The degree of the squeezing is dependent upon the two photon intensity I2, the cooperativity parameter C and the side-mode detuning.
