论文摘要
很少有周期脉冲提出了跟踪物质超快动态并驱动强场效应的重要工具。为了解决渴望光子的应用，使用了高平均功率激光器，但是不能直接提供100 fs脉冲持续时间。通过光谱宽扩大和分散补偿对激光脉冲进行压缩后，是克服此限制的最有效方法。在这里，我们演示了一个特别紧凑的设置，该设置将0.1 GW的峰值功率，Picsecond Laser变成2.9 GW峰值功率，8.2 FS源。 120倍的脉冲持续时间缩短是在两阶段混合多通的多板压缩设置中完成的。据我们所知，尚未据报道，较短的脉冲和更高的峰值能力仅从大量的多通细胞中迄今都迄今表达了杂种方法的力量。例如，它提出了紧凑，成本效益和高度重复率的ATTSEND来源。
Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers are used which, however, cannot directly provide sub-100 fs pulse durations. Post-compression of laser pulses by spectral broadening and dispersion compensation is the most efficient method to overcome this limitation. Here, we demonstrate a notably compact setup which turns a 0.1 GW peak power, picosecond laser into a 2.9 GW peak power, 8.2 fs source. The 120-fold pulse duration shortening is accomplished in a two-stage hybrid multi-pass, multi-plate compression setup. To our knowledge, neither shorter pulses, nor higher peak powers have been reported to-date from bulk multi-pass cells alone, manifesting the power of the hybrid approach. It puts, for instance, compact, cost-efficient and high repetition rate attosecond sources within reach.
