摘　　要：介绍了一种适合于日常高校光学或光电技术专业的研究生和高年级本科生熟悉、了解飞秒激光教学实验用的飞秒光纤激光器。该飞秒激光光源基于非线性旋转偏振效应被动锁模原理,输出脉冲宽度为440 fs、脉宽带宽积为0.362、中心波长在1560 nm附近、平均输出功率为12 mW、脉冲重复频率为31.15MHz。It is shown that a femtosecond fiber laser with a pulse repetition rate of 31 MHz,pulse width of 440 fs,central wavelength of 1560 nm and 12 mW average output power is successfully constructed.Such a laser source shows excellent stability with little frequency chirp,and it is compact,robust,lightweight,inexpensive,and easy to operate and maintain.With all these advantages,this laser is very suitable for both graduate and undergraduate students to study and experiment on femtosecond lasers.
