压缩光学纤维的时间自恢复
Temporal self-restoration of compressed optical filaments
摘要：
我们数值研究了自压缩光纤通过气体-玻璃-气体界面的传输。几个周期的光脉冲生存的非线性和色散的突然和短数量级的增加，即使所有保守的估计预测时间扩展或空间分裂。时空失真示出自愈后进一步传播时，脉冲在第二气体中重新聚焦。这种自我修复机制具有重要意义的脉冲压缩技术处理的双折射，并解释了这种来源的鲁棒性。
英文摘要：
We numerically investigate the propagation of a self-compressed optical filament through a gas-glass-gas interface. Few-cycle light pulses survive a sudden and short order-of-magnitude increase of nonlinearity and dispersion, even when all conservative estimates predict temporal spreading or spatial breakup. Spatio-temporal distortions are shown to self-heal upon further propagation when the pulse refocuses in the second gas. This self-healing mechanism has important implications for pulse compression techniques handled by filamentation and explains the robustness of such sources.
