Multiarm Michelson Interferometric System for the Shaping ofthe Laser Pulse——Ⅰ. Parameter Design

设计了纳秒级激光脉冲整形的多臂迈克耳逊干涉仪系统，并且从理论上分析了利用全光学手段对激光脉冲进行整形的过程。根据特定的输出波形计算了一组系统参数，比较了该组参数下实际输出的波形与参考波形的关系，指出在二倍到四倍初始脉宽之内，系统可以较好地进行整形。

A multiarm Michelson interferometric system for the shaping of the nanosecond laser pulse is designed. Process of the pulse shaping by an alloptical method is analyzed theoretically. According to a specially designed pulse shape for the purpose of ICF targeting usage, parameters of the system are calculated. In conclusion, when the width of the shaped laser pulse is in the range from 2 times to 4 times the width of the primary input pulse, the pulse shaping system works well.
