玻璃介质中感应超连续的研究

Study on induced spectral superbroadening in glass materials

在用一束弱的530nm超短激光脉冲入射到一块K_9玻璃中,在产生频谱上的超连续输出的基础上,同时把强的1060nm基频也入射到样品中,产生感应超连续,在不同的频率范围内观察到感应超连续功率谱增强4～15倍并且频谱也显著加宽。

When a weak 530nm ultrashort pulse propagates through K9 glass, it produces a spectral superbroadening. If an intense 1060nm laser pulse irradiates at the medium at the same time, an induced spectral superbroadening is obtained. 4-15 times enhancement of the spectral intensity in diffderent wave length range and obvious spectral broadening are observed.
