摘　　要：文章讨论了皮秒激光脉冲在单模光纤传输中光纤介质的色散及非线性折射率等效应对皮秒光信号的影响 .利用时间相关单光子计数系统 ,观测了皮秒激光脉冲在单模光纤中的展宽及皮秒自聚焦现象 。The influence of effects such as dispersion and nonlinear refractive index on picosecond laser pulse transmission in single-mode fiber is duscussed. Picosecond auto-focus phenomena and the broadening of the pulses have been observed using time-correlated single-photon counting. The aberration of picosecond pulses in fiber has also been detected and studied.
