摘要
A high repetition rate Tm：Ho：LuLiF master-oscillator and polarization-maintaining （PM） Tm-doped fiber power-amplifier system is presented. A ll.3-kHz, 0.4-nm line width, 0.89-W Tm：Ho：LuLiF seed laser is developed. Using a two-stage PM Tm-doped fiber power amplifier system, 32.4-W output power is obtained with 0.4-nm line width at a central wavelength of 2058.5 nm, corresponding to 0.66-W seed laser. The laser spectrum and pulse profile axe measured.
