本文综述了发射波长为2 μ m及更长的短脉冲光的锁模光纤激光器。工作在中红外（2-5 μ m）锁模区的稀土掺杂的二氧化硅和氟化物光纤激光器由于其在光谱学、非线性光学、激光外科、遥感和测距等方面的有用性而引起了人们的注意。石英光纤激光器基本上限于2.2 μ m以下的发射波长，而氟化物光纤激光器可以达到近4 μ m。与石英光纤相比，氟化物光纤的相对幼稚意味着该领域还有工作要做，以将锁模技术转化为超过2 μ m的系统。然而，随着最近一个稳定的，锁模3 μ m光纤激光器的演示，实现高性能的3 μ m级锁模光纤激光器的可能性看起来很有希望。(C)2014 Elsevier Inc.

Mode-locked fiber lasers emitting short pulses of light at wavelengths of 2 mu m and longer are reviewed. Rare-earth doped silica and fluoride fiber lasers operating in the mode-locked regime in the mid-IR (2-5 mu m) have attracted attention due to their usefulness to spectroscopy, nonlinear optics, laser surgery, remote sensing and ranging to name a few. While silica fiber lasers are fundamentally limited to emission wavelengths below 2.2 mu m, fluoride fiber lasers can reach to nearly 4 mu m. The relative infancy of fluoride fibers as compared to silica fibers means the field has work to do to translate the mode-locking techniques to systems beyond 2 mu m. However, with the recent demonstration of a stable, mode-locked 3 mu m fiber laser, the possibility of achieving high performance 3 mu m class mode-locked fiber lasers looks promising.
