	3.	For ultrashort pulsed beam propagation , to study the spatiotemporal instability . consider the time delayed response , a new instability region appeares . the position of this region and the magnitude of the gain depend on the characteristic raman response time 对于超短脉冲而言，介质的响应也不能看做瞬时的，如果考虑拉曼效应产生的响应的延迟，会产生一对增益边带，其位置和大小由响应时间决定。
	4.	The equation including the nonlinear dispersion , i . e . the modified nonlinear schrodinger ( mnls ) equation , is a better model . in this thesis , we take mnls solitons as a model for femtosecond soltions . then based on the recently developed direct perturbation theory for perturbed mnls equation , we study the raman self - frequency shift of femtosecond solitons and its suppression by the means of frequency filters . for this purpose , first , we define the physical parameters of mnls solitons ; next , through the direct perturbation theory for perturbed mnls equation , under adiabatic approximation , we obtain the evolving parameters of mnls soliton on our questions and then choose the parameters of frequency filters based on it ; at last , we directly numerically simulated our questions by split - step fourier ( ssf ) method after improving the arithmetic of the differentiation of the nonlinear item for satisfying mnls equation 本论文以mnls孤子作为光纤飞秒孤子的模型，通过新近建立的mnls孤子直接微扰理论，研究光纤中由拉曼效应引起的飞秒孤子在传输中的自频移，以及通过频率滤波对自频移的抑制。为此，首先给出描述mnls孤子的各物理量，然后用mnls孤子直接微扰理论，解析地得到这些问题绝热近似下的孤子参数演化，并由此选择频率滤波的参数，最后用分步傅里叶方法，在对非线性项微商的算法做出了适合于mnls孤子的改善后，对拉曼效应及频率滤波进行了直接数值模拟，其中频率滤波参数用微扰理论确定。
