| 摘 要： | 光纤激光器具有转换效率高、光束质量好、散热方便、结构紧凑等优点，是高功率激光器领域的研究热点。本文设计了温控、水冷系统使半导体激光二极管泵浦源稳定在工作波长。通过设计的包层泵浦功率剥除器，有效地剥离了未被掺镱（Yb3＋）双包层光纤吸收的泵浦光。采用20w的半导体二极管激光器作为泵浦源，5m长掺镱（Yb3＋）双包层光纤作为增益介质，光纤光栅作为腔镜，在泵浦功率为19w时，获得10．42W的激光输出，激光波长1062nm，光一光转换效率约54．8％。

| Abstract: | Fiber lasers combines advantages of high conversion efficiency, good beam quality, convenient cooling and compact config- uration, and has been studied extensively. A temperature-controlled cooler is designed to make the pumping source stable at working wavelength, and a power-stripper is used to strip the unabsorbed pumping from the ytterbium-dolSed double-clad fiber. 10.42 W output power is obtained with 19 W pumping, 5 m ytterbium-doped double-clad fiber gain medium and a fiber grating as the end mirror. The laser wavelength is 1 062 nm, and the optical-to-optical conversion efficiency is about 54.8%. |
