摘要

本文利用双金属固溶体 MAX 相 Ti2NbAlC2 可饱和吸收体，演示了中心波长为 1531.43 nm 的稳定 Q 开关光纤激光器。在泵浦功率为 300 mW 时，获得了 3.67 μs 的最短脉冲持续时间和 32.56 kHz 的最大重复频率。此外，Q 开关脉冲的最大输出功率为 1.08 mW，最大脉冲能量为 33.14 nJ。我们的研究结果表明，Ti2NbAlC2 是一种很有前途的可饱和吸收材料。双金属固溶体 MAX 相材料可被开发成性能卓越的新型非线性光子器件。

Bimetallic solid solution MAX phase Ti2NbAlC2 as saturable absorber for passively Q-switched Er3+-doped fiber laser

In this paper, we demonstrated a stable Q-switched fiber laser operation with a central wavelength of 1531.43 nm using a bimetallic solid solution MAX phase Ti₂NbAlC₂ saturable absorber. The minimum pulse duration of 3.67 μs and the maximum repetition rate of 32.56 kHz were acquired at the pump power of 300 mW. Furthermore, the Q-switched pulse has a maximum output power of 1.08 mW and a maximum pulse energy of 33.14 nJ. Our results indicate that the Ti₂NbAlC₂ is a promising saturable absorber material. The bimetallic solid solution MAX phase materials may be developed as novel nonlinear photonic devices with outstanding performance.
