title = "High power single-frequency laser output from a diffusion-bonded monolithic nonplanar Ho:YAG ring oscillator",
abstract = "In this paper, an experimental investigation of monolithic diffusion-bonded nonplanar Ho:YAG ring oscillator(NPRO) operated at 2.09μm was presented. A theoretical thermal model for the diffusion-bonded NPRO was established, the thermal effect of the diffusion-bonded Ho:YAG NPRO and un-bonded NPRO were calculated and compared in detail. A diode-pumped Tm-YLF solid-state laser was used to pump the diffusion-bonded Ho:YAG NPRO, a stable singlefrequency output power of up to 12.5W was obtained at 2.09μm with a slope efficiency of 46.3\%. The beam quality M2-factors were less than 1.3 in both x-and y-directions.",
