四程放大自动准直系统数学模型研究

针对高功率激光装置四程放大系统的特点,利用矩阵光学原理,建立了四程放大准直系统的数学模型;基于此模型,设计了四程放大系统的准直调整方案;得出了近、远场偏移量与调整量关系的解析解.

Beam automatic alignment system is used to implement beam adjustment. Basing on the principle of matrix optics, the mathematical model for auto-alignment in four-pass amplifier is built by analyzing the properties of this system. Using this model, the scheme of beam alignment is designed, and the analytical solutions of the amounts of near field adjustment and far field adjustment are obtained, respectively.
