运用分步傅里叶法解非线性薛定谔方程来对超短脉冲在充满惰性气体的中空光波导中的展宽 与压缩进行数值模拟计算.模拟证明，分段光纤展宽光谱具有损耗小，可能压缩脉冲窄等潜 在优点，对在实验中进一步压缩脉冲到周期量级有指导意义.

The spectrum broadening and pulse compression of the ultrashort pulse propagatio n in cascaded hollow fibers,by solving the generalized nonlinear Schrdinger eq uation with the split_step Fourier Method,are discussed.The simulation shows tha t the technique using cascaded hollow fibers is a reliable route to achieve few to mono-cycle pulses of high energy.-
