abstract = "We report on the free-running characteristics of a monolithic Ho:YAG nonplanar ring oscillator (NPRO) for use as a seed laser. The solid-state laser is resonantly pumped by an in-house developed narrow linewidth thulium-doped fiber laser emitting at a wavelength of 1910 nm. We tested different laser crystal coatings to obtain different output power and wavelength properties. We achieve up to 53 mW output power at a wavelength of 2090 nm and up to 380 mW at 2122 nm with single-frequency operation while maintaining excellent beam quality and a high degree of linear polarization with a polarization extinction ratio (PER) of > 20 dB. The free-running laser shows a high power-stability over a broad frequency range, as evidenced by our relative intensity noise (RIN) analysis for frequencies from 1 mHz to 150 kHz.",
