摘　　要：基于光的色散和棱镜光谱仪的特点,采用等光程方法推导了紧凑累加型二棱镜系统二阶和三阶色散的表达式,并分析具体实例。通过计算机模拟得出二阶和三阶色散曲线,为可调谐激光的线宽压窄提供了一定的理论依据。The character of the dispersion of light and prism was introduced. Using equal-light-path method, the formulas of second-order and third-order dispersion of additive-type two-prism sequence were derived. The formulas are useful in evaluating the dispersion of two-prism sequence that can be inserted in self-mode-locked lasers like Ti： sapphire laser. The diagram of dispersion by analogue calculate of computer was got.
