我们研制了一个无光纤的1 TW全钕玻璃啁啾脉冲放大激光系统，该系统使用高对比度的0.8-1.4 ps脉冲直接从钕玻璃反馈控制振荡器产生。该系统仅采用光栅扩展和压缩，产生干净的（~10（7）对比度）1-J，1- 1.4-ps的再压缩脉冲，而无需额外的脉冲清洗。来自振荡器的干净微焦耳能量脉冲需要比cw振荡器方案更少的后续放大，从而最小化增益带宽变窄，并提供与放大的受激发射背景的改进的对比度。
We have developed a fiberless 1-TW all-Nd:glass chirped-pulse-amplification laser system that uses high-contrast 0.8-1.4-ps pulses produced directly from a Nd:glass feedback-controlled oscillator. Employing grating-only expansion and compression, the system produces clean (~10(7) contrast ratio) 1-J, 1- 1.4-ps recompressed pulses without added pulse cleaning. Clean microjoule-energy pulses from the oscillator require less subsequent amplification than cw oscillator schemes, thereby minimizing gain-bandwidth narrowing and offering improved contrast with amplified stimulated emission background.
