在“反应显微镜”中进行光电离后的电子-离子同步检测是研究原子和分子动力学的一种非常有力的工具。然而，该工具在阿秒科学领域的实施迄今为止相当有限，因为缺乏能够提供每个脉冲具有足够能量的低周期脉冲的高重复率激光源。本文介绍了一种非共线光参量放大器（NOPA）的研制，该放大器能够输出持续时间低于6fs的载波包络相位（CEP）稳定脉冲，脉冲能量在几μ J范围内。结合高重复率源和在这个高频率操作的反应显微镜的潜力，证明了在一个原理证明的实验强场电离的Ar原子。(c) 2013年美国光学学会
Coincident electron-ion detection after photoionization in a "reaction microscope" is a very powerful tool to study atomic and molecular dynamics. However, the implementation of this tool in the field of attosecond science has so far been rather limited, due to the lack of high repetition rate laser sources capable of delivering few-cycle pulses with sufficient energy per pulse. In this article, the development of a Non-collinear Optical Parametric Amplifier (NOPA) capable of delivering Carrier-Envelope Phase (CEP) stable pulses with sub-6 fs duration and pulse energies in the few-mu J range is presented. The potential of combining the high repetition rate source and a reaction microscope operating at this high frequency is demonstrated in a proof-of-principle experiment on strong field ionization of Ar atoms.
