非共线光参量放大器 (NOPA) 已成为在高重复率和高平均功率下放大载波包络相位 (CEP) 稳定的少周期脉冲的领先技术。在这封信中，报告了以 100 kHz 重复率运行的 NOPA，在压缩之前可提供超过 24 W 的平均功率。放大的带宽支持低于 7 fs 的脉冲持续时间，并实现了接近变换极限的脉冲压缩。证明了扩增后的 CEP 稳定性。该系统为具有电子-离子符合检测功能的阿秒泵浦探针光谱学铺平了道路。 (C) 2017年美国光学学会
Noncollinear optical parametric amplifiers (NOPAs) have become the leading technique for the amplification of carrier-envelope phase (CEP)-stable, few-cycle pulses at high repetition rate and high average power. In this Letter, a NOPA operating at a repetition rate of 100 kHz delivering more than 24 W of average power before compression is reported. The amplified bandwidth supports sub-7 fs pulse durations and pulse compression close to the transform limit is realized. CEP stability after amplification is demonstrated. The system paves the way to attosecond pump-probe spectroscopy with electron -ion coincidence detection. (C) 2017 Optical Society of America
