摘　　要：为了获得不同中心波长的锁模脉冲,采用带有保偏光纤的Sagnac环滤波器和半导体可饱和吸收镜搭建了结构紧凑的可调谐锁模激光器,并进行了实验验证。结果表明,当该激光器工作在单波长锁模状态时,具有良好的波长调谐功能,其输出波长在1031 nm~1040 nm范围内连续可调;该激光器还能输出稳定的双波长异步脉冲序列,两波长间隔在10 nm左右,且各波长的带宽可通过偏振控制器调节。该研究可以为搭建结构紧凑的可调谐激光器提供设计方案。In order to obtain mode-locked pulses with different center wavelengths,a compact tunable mode-locked laser was built by using Sagnac loop filter with polarization maintaining fiber and semiconductor saturable absorber mirror.And the experimental verification was carried out.The results show that,the laser has a good wavelength tuning function when it operates in a single wavelength mode locked state,and its output wavelength is continuously adjustable in the range of 1031 nm to 1040 nm.The laser can also output a stable dual wavelength asynchronous pulse sequence,with the interval between the two wavelengths about 10 nm,and the bandwidth of each wavelength can be adjusted by the polarization controller.This research can provide a design scheme for building a compact tunable laser.
