通过在差动泵浦的 2 m 长复合拉伸柔性中空光纤中圆偏振 8 mJ 脉冲的光谱展宽，产生具有 3 mJ 能量的载波包络相位稳定 4 fs 近红外脉冲。使用二次谐波发生频率分辨光门控 (SHG-FROG) 和 SHG d 扫描方法对脉冲进行表征。
Carrier-envelope phase stable 4 fs near-IR pulses with 3 mJ energy were generated by spectral broadening of circularly polarized 8 mJ pulses in a differentially pumped 2 m long composite stretched flexible hollow fiber. The pulses were characterized using both second-harmonic generation frequency-resolved optical gating (SHG-FROG) and SHG d-scan methods.
