本文从全量子理论观点分析了共振多光子过程,采用相互作用表象及Laplace变换得到一多元线性代数方程组,并获得其特征行列式的解析表达式,从而得到多光子跃迁几率的解析解。比起已有的方法简洁得多。

In this article we analyse the process of resonant multiphoton from the view point of full quantization theory. Using the interaction representation and Laplace Transform, a group of linear Algebra equations and then the analytic repesentation of its charateristic determinant are obtained. The analytic solution of multiphoton transition probability is at last obtained, and it is much simpler than other previous methods.
