超短激光脉冲在非线性光纤中的传播

Propagation of the Ultrashort Laser Pulse in Nonlinear Fiber

研究了非线性光纤中自相位调制导致光脉冲频谱展宽的详细物理过程，以此为光纤中光孤子产生的物理过程作准备。

Study the detailed physical process of the self phase modulation induced spectral broadening.This must be taken as prepare the ground for the founding of optical soliton in nonlinear fiber.
