A high-power 83 W cladding-pumped Tm3+-Ho3+-doped silica fiber laser is reported. Using bidirectional 793 nm diode pumping, a maximum slope efficiency of 42% was produced after a threshold launched pump power of 12 W was exceeded. The laser operated at wavelengths near 2105 nm with moderate beam quality, i.e., M2 approximately 1.5. Further power scaling of the fiber laser was limited by thermal failure of the fiber ends.
报道了一种高功率83W包层泵浦掺Tm3+-Ho3+石英光纤激光器。采用双向793nm二极管泵浦，在超过12W的阈值泵浦功率后，产生了42%的最大斜率效率。该激光器在2105nm附近的波长下运行，光束质量适中，即M2约为1.5。光纤激光器的进一步功率扩展受到光纤端面热失效的限制。
