摘要
利用非线性放大环镜作为人工可饱和吸收体, 在铥钬共掺光纤激光器中研究了多孤子脉冲现象.在同一泵浦功率不同偏振状态下, 实验不仅获得了稳定的单个孤子脉冲, 还观察到由单个孤子脉冲演化为2至4个孤子的锁模脉冲现象; 在保偏光运行条件下增加泵浦功率, 获得了孤子能量量化的演化过程.所得结果主要源于腔内弱的双折射效应等效的滤波器具有限制增益带宽和诱导多脉冲产生的作用.而调节偏振控制器对腔内增益的改变, 是不同类型多脉冲现象出现的主要原因.研究结果对2 μm波段非线性放大环镜光纤激光器多孤子锁模脉冲动力学特性的研究具有一定参考价值.
Abstract
The phenomenon of mutli-soliton pulse is studied in Tm/Ho-codoped fiber laser based on a nonlinear amplified loop mirror as an artificial saturable absorber. By simply adjusting the polarization angle of Polarization Controller (PC), the experiment not only obtained a stable single-soliton pulse, but also observed the pulse sequences of the two-soliton, three-soliton and four-soliton. Increase the pump power under polarization maintaining operation, the evolution of soliton energy quantization is also obtained. The weak birefringence effect in the cavity is important for limiting the gain bandwidth and inducing the generation of multi-soliton. Adjusting the PC is equivalent to changing the gain in the cavity, which is the main reason for the formation of different multiple pulses states. We believe that the results obtained will be helpful in the investigation of multi-soliton pulses dynamics in 2 μm mode-locked fiber lasers.
