超高功率2.04μm激光在超紧凑型掺钬锗酸铅光纤中的应用。（原英文文本可能表述不太准确，推测是这个意思，不然单纯从字面不好理解完整逻辑，正常应该是关于该激光在光纤中的某种研究之类的表述）你可检查下原文是否准确，若有疑问随时告知我。若仅按字面准确翻译就是：高功率2.04μm激光在超紧凑型掺钬锗酸铅光纤中。

Abstract

A highly Ho-doped single-mode lead germanate glass fiber is developed for compact ∼2 μm lasers. Over 600 mW of laser output operating at 2.04 μm is demonstrated in a 2 cm-long active fiber. The slope efficiency reaches ∼34.9% with respect to the launched 1.94 μm laser pump power. To the best of our knowledge, this is the highest laser output power demonstrated within a few centimeters of a Ho-doped fiber. This result shows that the fiber is highly promising for high-power single-frequency laser applications.

摘要

一种高掺钬单模锗酸铅玻璃光纤被开发用于紧凑型约2μm激光器。在一根2厘米长的有源光纤中，展示了超过600毫瓦、波长为2.04μm的激光输出。相对于发射的1.94μm激光泵浦功率，斜率效率达到约34.9%。据我们所知，这是在几厘米长的掺钬光纤中展示出的最高激光输出功率。这一结果表明，这种光纤在高功率单频激光应用方面极具前景。
