摘要 实现了一种新型的激光脉冲整形系统,该系统使用了一个由孔径耦合带状线(ACSL)电脉冲整形器驱动的电光调制器.一个电脉冲整形器由两条通过其公共接地板上的耦合孔径发生耦合作用的带状传输线所组成的四端口装置.更换具有不同耦合孔径的公共接地板,该电脉冲整形发生器可以具有150 ps时间结构的任意整形电脉冲.将任意整形的电脉冲输入到电光调制器上,就可以得到任意整形的激光脉冲.利用该系统,激光脉冲整形系统能够产生具有150 ps前后沿,1~3 ns脉冲宽度可调、高对比度、光滑过渡以及任意整形的激光脉冲. A new laser pulse-shaping system using an electro-optic modulator driven by an aperture-coupledstriplines (ACSL) electrical-waveform generator has been discussed in this paper. The ACSL electrical-waveform generator consists of two striplines coupled through an aperture in their common ground plane. Replacing the aperture layer, the electrical-waveform can produce arbitrary electrical pulse with 150 ps structure. Giving the arbitrary electrical pulse to the electro-optic modulator, arbitrary optic pulse can be gotten. By the new technique, the laser pulse-shaping system is capable of producing arbitrarily shaped laser pulses with about 150 ps structure, 1-3 ns pulse envelope, high contrast waveform and slippery transition waveform.
