本文报道了一种2.07 μm波段可调谐主动锁模光纤激光并在室内模拟大气湍流条件下进行传输特性研究。增益介质为1.5 m长的掺钬光纤，主动锁模通过LiNbO3强度调制器在腔内引入周期强度调制实现。腔内引入非线性偏振旋转效应实现波长2058.4 nm~2078.6 nm可调谐。实验获得了稳定的基频锁模脉冲和10阶，24阶，48阶谐波锁模脉冲，对应频谱信噪比为66.79 dB、61.37 dB、54.82 dB和49.66 dB。锁模脉冲经过数字调制后在实验室内大气湍流模拟池中进行传输，分别获得了ΔT为70 ℃，140 ℃和210 ℃时三种湍流强度和背对背条件下的眼图；与背对背条件相比，在ΔT=210 ℃时光信噪比降低了9.14 dB。
