关键词：时空不稳定性 超短脉冲 时空聚焦 色散效应 自陡峭效应
基于非线性包络方程研究了非线性色散介质中的时空不稳定性,得到了有时空聚焦效应、任意高阶色散效应和自陡峭效应情形下不稳定性调制的增益谱的表达式.结果表明：在正常和反常两种群速度色散情形下,时空聚焦效应都会导致出现新的不稳定性区域且对原来的增益谱的最大增益没有影响,但使谱的范围收缩,其中在正常群速度色散情形收缩较大,它完全抑制了高频成分的增长,而在反常群速度色散情形收缩则很小.所有的奇数阶色散效应都不对时空不稳定性产生影响,而所有的偶数阶色散效应都影响时空不稳定性增益谱的范围而不影响它的最大增益,其中四阶色散效应与时空聚焦效应对不稳定性的作用相似.自陡峭效应的主要影响是使调制增益下降,其中它对时空聚焦效应所导致的新区域的影响更大.

再答： Spatiotemporal instability of ultrashort pulse space-time focusing dispersion effect of self-steepening nonlinear equation based on the spatiotemporal nonlinear dispersive medium instability, expression gain space focusing effect, arbitrary high order dispersion effect and self-steepening effect under the condition of the spectrum modulation instability is obtained. The results show that: in normal and abnormal rate of two populations the dispersion situation, space-time focusing effect will lead to not affect maximum gain instability region of new and original gain spectrum, but to shrink the scope of spectrum, the larger contraction in normal group velocity dispersion, it completely inhibited the growth of high frequency components, in the anomalous group velocity dispersion situation contraction is small. The odd order dispersion effect all right spatiotemporal instability impact, and even order dispersion effect all affect the spatiotemporal instability gain spectrum range without affecting its maximum gain, the effect of the four order dispersion effect and space-time focusing effect on instability similar. Since the main effect effect is steep the modulation gain decreases, which affect regional it lead to the space-time focusing effect of the greater.
