We experimentally demonstrated a stable, high-average-power, continuous-wave (CW) passively mode-locked Er(3+)-doped ZBLAN fiber laser at 2.8 μm based on a semiconductor saturable absorber mirror. A stable mode-locked laser with a signal-to-noise ratio of 52 dB and a slope efficiency of 14% was obtained. The highest average output power in excess of 1 W was generated at the incident pump power of 8.2 W, with a pulse repetition rate of 22.56 MHz and pulse duration of 25 ps. To the best of our knowledge, this is the highest average output power of a CW mode-locked ZBLAN fiber laser in the mid-infrared wavelength regime up to now.
我们通过实验证明了一种基于半导体可饱和吸收镜的稳定、高平均功率、连续波（CW）被动锁模掺铒ZBLAN光纤激光器，其波长为2.8μm。获得了一个信噪比为52dB、斜率效率为14%的稳定锁模激光器。在8.2W的入射泵浦功率下，产生了超过1W的最高平均输出功率，脉冲重复频率为22.56MHz，脉冲持续时间为25ps。据我们所知，这是迄今为止中红外波长范围内连续波锁模ZBLAN光纤激光器的最高平均输出功率。
