论文摘要
我们展示了以400 nm为中心的7.6 fs近紫外脉冲通过带有超薄核心壁的AR填充空心核心风格的光子晶体纤维中的8倍孤子效应的自我压缩产生。有效压缩长度和孤子顺序的分析计算允许调整实验参数，以及光纤中非线性脉冲动力学的数值建模，可以准确预测自动压缩脉冲的光谱谱曲线。在沿光纤路径从光纤到诊断的光学元件引入的相失真的补偿后，脉冲能的71％在主颞叶中，峰值功率超过0.2 gw。便捷的设置为光谱，化学和材料科学方面的时间分辨研究开辟了新的机会。
We demonstrate generation of 7.6 fs near-UV pulses centered at 400 nm via 8-fold soliton-effect self-compression in an Ar-filled hollow-core kagomé-style photonic crystal fiber with ultrathin core walls. Analytical calculations of the effective compression length and soliton order permit adjustment of the experimental parameters, and numerical modelling of the nonlinear pulse dynamics in the fiber accurately predict the spectro-temporal profiles of the self-compressed pulses. After compensation of phase distortion introduced by the optical elements along the beam path from the fiber to the diagnostics, 71% of the pulse energy was in the main temporal lobe, with peak powers in excess of 0.2 GW. The convenient set-up opens up new opportunities for time-resolved studies in spectroscopy, chemistry and materials science.
