摘要:

我们报道了一种简单的方法来控制CPA激光链系统中的主要时空耦合,使用一个专门设计的色偶在一个发散光束配置。双合透镜的居中允许控制CPA激光链的空间啁啾,而其在发散光束中的纵向位置使得能够控制宽动态范围内的纵向色差量。该技术的性能进行评估,通过测量主要的时空耦合与一个简单的方法,基于超快脉冲整形器,它允许选择窄窗口的频谱。

英文摘要:

We report a straightforward method to control main spatio-temporal couplings in a CPA laser chain system using a specially designed chromatic doublet in a divergent beam configuration. The centering of the doublet allows for the control of the spatial chirp of the CPA laser chain, while its longitudinal position in the divergent beam enables the control of the amount of longitudinal chromatism in a wide dynamic range. The performance of this technique is evaluated by measuring main spatio-temporal couplings with a simple method, based on an ultrafast pulse shaper, which allows for a selection of narrow windows of the spectrum.
