The operation of a diode-pumped Tm-doped silica fiber laser that uses the cladding-pumping arrangement to produce high-power cw output at wavelengths near 2 microm is reported. We obtained a maximum output power of 5.4 W at a slope efficiency of 31% with respect to the launched pump power at a total optical-to-optical efficiency of 22%. The fiber-laser output wavelength was tuned between 1.880 and 2.033 microm by adjustment of the fiber length, with >4W of power obtainable from 1.94 to 2.01 microm. Self-pulsations detected in the output from the double-clad fiber laser may indicate the presence of ion-clustering effects.
报道了一种二极管泵浦掺铥石英光纤激光器的运行情况，该激光器采用包层泵浦结构，在波长接近2微米处产生高功率连续波输出。我们获得了5.4瓦的最大输出功率，相对于发射泵浦功率的斜率效率为31%，总光光效率为22%。通过调整光纤长度，光纤激光器的输出波长在1.880至2.033微米之间调谐，在1.94至2.01微米之间可获得大于4瓦的功率。在双包层光纤激光器输出中检测到的自脉动可能表明存在离子聚集效应。
