Abstract

An all-solid-state longitudinally diode-pumped Nd:glass chirped-pulse-amplification laser system producing pulses of 50-MW peak power has been developed. The diode-pumped Nd:glass regenerative amplifier produces pulses with energies as great as 56microJ at a 1-kHz repetition rate and pulse durations as short as 450 fs after compression in a compact single holographic-transmission-grating stretcher-compressor arrangement. Further, spectral gain shaping was shown to extend the bandwidth that was supported in the low-gain amplifier. To the best of our knowledge, this system provides the highest peak and average power obtained from a directly diode-pumped femtosecond laser.

摘要

已开发出一种全固态纵向二极管泵浦的钕玻璃啁啾脉冲放大激光系统，该系统能产生峰值功率为50兆瓦的脉冲。二极管泵浦的钕玻璃再生放大器在1千赫兹的重复频率下产生能量高达56微焦的脉冲，在紧凑的单全息透射光栅展宽器 - 压缩器装置中压缩后脉冲持续时间短至450飞秒。此外，光谱增益整形被证明可扩展低增益放大器中支持的带宽。据我们所知，该系统提供了从直接二极管泵浦飞秒激光器获得的最高峰值功率和平均功率。
