We have developed a diode-pumped tunable 3 μm fiber laser with a cw output power of the order of 10 W with the use of an erbium-doped ZBLAN fiber. A tunability range of 110 nm (2770 to 2880 nm) with an output power between 8 and 11 W was demonstrated. As the pump power was increased, the center of the wavelength range was shifted toward longer wavelengths, but the width of the wavelength range was largely unaffected. The total tunability range for various pump power levels was 170 nm (2710 to 2880 nm). To our knowledge, this is the highest performance (output power and tunability) obtained from a tunable 3 μm fiber laser.
我们利用掺铒 ZBLAN 光纤研制出了一台连续波输出功率约为 10 W 的二极管泵浦可调谐 3 μm 光纤激光器。该激光器的调谐范围为 110nm（2770nm 至 2880nm），输出功率在 8 W 至 11 W 之间。随着泵浦功率的增加，波长范围的中心逐渐移向长波长，但波长范围的宽度基本保持不变。在不同的泵浦功率水平下，总的调谐范围为 170nm（2710nm 至 2880nm）。据我们所知，这是可调谐 3 μm 光纤激光器中获得的最高性能（输出功率和调谐范围）。
