ABSTRACT

Contemporary ultrafast science requires reliable sources of high-energy few-cycle light pulses. Currently two methods are capable of generating such pulses: post compression of short laser pulses and optical parametric chirped-pulse amplification (OPCPA). Here we give a comprehensive overview on the post-compression technology based on optical Kerr-effect or ionization, with particular emphasis on energy and power scaling. Relevant types of post compression techniques are discussed including free propagation in bulk materials, multiple-plate continuum generation, multi-pass cells, filaments, photonic-crystal fibers, hollow-core fibers and self-compression techniques. We provide a short theoretical overview of the physics as well as an in-depth description of existing experimental realizations of post compression, especially those that can provide few-cycle pulse duration with mJ-scale pulse energy. The achieved experimental performances of these methods are compared in terms of important figures of merit such as pulse energy, pulse duration, peak power and average power. We give some perspectives at the end to emphasize the expected future trends of this technology.

高能几周期脉冲:后压缩技术

摘要

当代超快科学需要可靠的高能数周期光脉冲源。当前,有两种方法能够生成这样的脉冲:短激光脉冲的后压缩和光学参量chi脉冲放大(OPCPA)。在这里,我们对基于光学克尔效应或电离的后压缩技术进行了全面概述,尤其着重于能量和功率缩放。讨论了相关的后压缩技术类型,包括散装材料中的自由繁殖,多板连续体生成,多通道细胞,长丝,光子晶体纤维,中空纤维和自压缩技术。我们提供了有关物理原理的简短理论概述,并详细介绍了后压缩的现有实验实现,尤其是那些能够以mJ级脉冲能量提供短周期脉冲持续时间的脉冲。根据重要的性能指标,例如脉冲能量,脉冲持续时间,峰值功率和平均功率,比较了这些方法获得的实验性能。最后,我们给出一些观点以强调该技术的预期未来趋势。
