We present a tunable, high power cladding-pumped holmium doped fiber laser. The laser generated >15 W CW average power across a wavelength range of 2.043 - 2.171 μm, with a maximum output power of 29.7 W at 2.120 μm. The laser also produced 18.2 W when operating at 2.171 µm. To the best of our knowledge this is the highest power operation of a holmium doped laser at a wavelength >2.15 µm. We discuss the significance of background losses and fiber design for achieving efficient operation in holmium doped fibers.
我们展示了一种可调谐、高功率包层泵浦掺钬光纤激光器。该激光器在2.043 - 2.171μm波长范围内产生了大于15W的连续波平均功率,在2.120μm处的最大输出功率为29.7W。该激光器在2.171μm波长工作时也产生了18.2W的功率。据我们所知,这是掺钬激光器在波长大于2.15μm时的最高功率运行。我们讨论了背景损耗和光纤设计对于实现掺钬光纤高效运行的重要性。
