论文摘要
我们报告了一种直接的方法，该方法是在CPA激光链系统中使用特殊设计的彩色束配置中的主要时空耦合。双子座的核心允许控制CPA激光链的空间呼吸，而其在发散束中的纵向位置可以控制在广泛的动态范围内的纵向染色体量。通过基于超快脉冲塑形器测量简单的方法来评估该技术的性能，从而可以选择狭窄的光谱窗口。
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.
