Abstract

We present an optical parametric chirped pulse amplifier (OPCPA) delivering CEP-stable ultrashort pulses with 7 fs, high energies of more than 1.8 mJ and high average output power exceeding 10 W at a repetition rate of 6 kHz. The system is pumped by a picosecond regenerative thin-disk amplifier and exhibits an excellent long-term stability. In a proof-of-principle experiment, high harmonic generation is demonstrated in neon up to the 61 order.

摘要

我们展示了一种光学参量啁啾脉冲放大器（OPCPA），它能产生中心能量相位（CEP）稳定的超短脉冲，脉冲持续时间为7飞秒，能量超过1.8毫焦，在6千赫兹的重复频率下平均输出功率超过10瓦。该系统由一个皮秒再生薄片放大器泵浦，具有出色的长期稳定性。在原理验证实验中，在氖气中展示了高达61阶的高次谐波产生。
