A diode-laser-pumped neodymium-doped fiber laser is presented. For a launched pump power of 85 mW, the fiber laser had a cw output power of 43 mW, which is approximately an order of magnitude greater output power than any previously reported diode-pumped neodymium fiber laser operating on the 4F(3/2)-4I(9/2) transition, which covers the 900-950-nm region. The fiber laser had a threshold power of 10 mW and a slope efficiency of 58% with respect to launched pump power. Tuning with a diffraction grating was obtained from 896 to 937 nm with narrow-band output powers as high as 32 mW. Emission was also obtained at 939.5 nm with use of a fiber Bragg grating as the output reflector.
介绍了一种二极管激光泵浦掺钕光纤激光器。对于85毫瓦的泵浦功率输入，该光纤激光器的连续波输出功率为43毫瓦，这比之前报道的任何基于4F(3/2)-4I(9/2)跃迁（覆盖900 - 950纳米区域）的二极管泵浦钕光纤激光器的输出功率大约高一个数量级。该光纤激光器的阈值功率为10毫瓦，相对于泵浦功率输入的斜率效率为58%。使用衍射光栅调谐时，可在896至937纳米范围内实现高达32毫瓦的窄带输出功率。使用光纤布拉格光栅作为输出反射器时，还可在939.5纳米处获得发射。
