ABSTRACT
We present a high-power continuous-wave (CW) TmYAG single-crystal fiber (SCF) laser wing-pumped by laser diodes at 791â
nm. A maximum output power of 63.3 W is achieved at â¼ 2.01â
µm, corresponding to a slope efficiency of 34.2%. This is, to the best of our knowledge, the highest power obtained from the SCF laser in the 2â
µm spectral range. In addition to the wing pumping scheme, the large surface-to-volume ratio of such fiber-geometry crystalline rod with diffusion-bonded undoped YAG end caps are benefited for the spatial uniform distribution of pump intensity and thermal load, and thus improving the power scalability.
