We report a passively mode-locked fiber oscillator based on thulium-doped large-mode-area (LMA) fiber. Reliably mode-locking soliton operation can be readily achieved after the suppression of the higher-order modes by using mode field adapters in combination with coiling fiber method. The laser delivers 600-fs level pulses at $2~\mu \text{m}$ with an average power of up to 243 mW and a repetition rate of ~53.7 MHz. The output corresponds to a maximum pulse energy of 4.5 nJ, >5 times larger than that of a similar homemade mode-locked Tm laser with the LMA fibers replaced by single mode fibers, coinciding with theoretical prediction. The successful demonstration of our soliton mode-locked LMA fiber laser at $2~\mu \text{m}$ offers another strategy for high performance ultrafast fiber sources at mid-infrared region.

孤子锁模大模式面积掺铥光纤振荡器

我们报告了一种基于掺铥大模式面积 (LMA) 光纤的被动锁模光纤振荡器。在抑制高阶模式后,通过使用模式场适配器结合盘绕光纤方法可以很容易地实现可靠的锁模孤子操作。激光器以 600-fs 级脉冲提供 $2~\mu \text{m}$ 平均功率高达 243 mW,重复率约为 53.7 MHz。输出对应于 4.5 nJ 的最大脉冲能量,比类似的自制锁模 Tm 激光器大 5 倍,其中 LMA 光纤被单模光纤取代,与理论预测一致。我们的孤子锁模 LMA 光纤激光器在 $2~\mu \text{m}$ 为中红外区域的高性能超快光纤源提供了另一种策略。
