激光腔内压缩态光的产生

压缩态光的产生必须借助于非线性相互作用过程,由于转换效率的限制,通常产生的压缩态光强度是较低的。本文从理论上给出了压缩态光产生的一般条件,在此基础上推断出一个包含激光的放大与非线性相互作用过程在内的系统,既能实现光强的放大,又能导致腔内场振幅正交分量之一的起伏的压缩。关键词：

GENERATION OF SQUEEZING LIGHT IN A LASER CAVITY

Generation of squeezing light depends on the nonlinear optical processes. Its intensirv is usually low owing to the limitation of the conversion efficiency. In this paper, the general condition for producing squeezing light is given. According to this condition, the conclusion is obtained that a laser cavity with a nonlinear medium and a gain medium can sime-ltaneously amplify the light intensity and reduce the quantum fluctuation of one quadrature phase component of the light field.
