Abstract

A folded geometry acousto-optic modulator spatial pulse shaper has been designed for shaping individual pulses from a high power amplified laser. The design preserves the capability of computer programmable amplitude and phase modulation of femtosecond laser pulses. An additional application of genetic algorithm optimization approach for compressing a stretched pulse is also demonstrated for such a pulse shaper. Spectrally and temporally resolved optical gating technique is used to characterize the shaped pulses.

摘要

一种折叠式几何声光调制器空间脉冲整形器已被设计用于对高功率放大激光器发出的单个脉冲进行整形。该设计保留了对飞秒激光脉冲进行计算机可编程幅度和相位调制的能力。对于这种脉冲整形器，还展示了遗传算法优化方法在压缩拉伸脉冲方面的额外应用。光谱和时间分辨光学选通技术用于表征整形后的脉冲。
