Abstract

Second harmonic generation in an air-silica microstructured optical fiber pumped by subnanosecond pulses is used in order to initiate modulation instability processes in normal and anomalous dispersion regimes. This allows us to generate an ultra wide and flat supercontinuum (350-1750 nm), covering the entire transparency window of silica and exhibiting a singlemode transverse profile in visible range.

摘要

利用亚纳秒脉冲泵浦的空气-二氧化硅微结构光纤中的二次谐波产生，以便在正常和反常色散区域引发调制不稳定性过程。这使我们能够产生一个超宽且平坦的超连续谱（350 - 1750纳米），覆盖二氧化硅的整个透明窗口，并在可见光范围内呈现单模横向分布。
