利用光纤—光栅对1.06μm皮秒光脉冲压缩

COMPRESSION Of 1.06μm PS PULSES BY USING FIBER GRATING-PAIR

本文报道了利用光脉冲在10m单模光纤中传播所产生的自相位调制(SPM)、互相位调制(XPM)、群速色散(GVD)和受激喇曼散射(SRS)的共同作用,实现光脉冲光谱和时间加宽,经光栅对线性啁啾补偿后,将脉宽15ps的1.06μm光脉冲压缩至小于6ps,能量大于100nJ,压缩比>2.5。

the paper reported that combined action of self-and cross-phase modulation (SPM and XPM), group-velocity dispersion (GVD), and stimulated Raman scattering (SRS) experienced by pulses propagatingalong a 10m-long single-mode optical fiber leads to spectrally and temporally broadened pulses exiting the fiber. After linear chirp is compensated by a grating-pair. The experimental results of less than 6ps optical pulse comperessed froml15ps pulse have been got. Compression ratio is more than 2.5.
