提出了利用1570nm的连续激光和1565nm的脉冲激光混合抽运铥/钬共掺光纤获得脉冲激光输出的方案,搭建相应的实验平台,得到了混合抽运方式下的2μm稳定脉冲激光输出。同时进行了直接增益开关方式获得脉冲输出的实验。对两种方式获得的脉冲进行了对比。实验结果表明,在相同输出功率水平下,混合抽运方式获得的脉冲激光更加稳定,能量浮动小于5%。相对于直接增益开关方式,混合抽运方式在获得更加稳定的脉冲激光输出上具有一定优势。但直接增益开关方式获得的激光输出的脉宽要小于混合抽运方式获得的激光脉宽。 Proposed the use of 1570nm continuous laser and 1565nm pulsed laser hybrid pumping 铥 / holmium co-doped fiber to obtain a pulsed laser output program, set up the corresponding experimental platform, the hybrid pumping mode 2μm stable pulsed laser output. At the same time, a direct gain switching method to obtain the pulse output experiment. The pulse obtained by the two methods were compared. The experimental results show that the pulsed laser obtained by hybrid pumping is more stable and the energy fluctuation is less than 5% at the same output power level. Compared with the direct gain switching mode, the hybrid pumping mode has certain advantages in obtaining a more stable pulse laser output. However, the pulse width of the laser output obtained by the direct gain switching method is smaller than that obtained by the hybrid pumping method.
