Abstract

We report a novel cooling technique for solid-state laser, which provides opportunity for liquid nitrogen temperature. The cooling holder does not have any windows on the laser beam path in order to minimize dispersion-related effects and nonlinear absorption under femtosecond laser operation. cw laser oscillation of 4% Yb³⁺-doped Y₂O₃ ceramics at 120 K temperature and 450 mW output power at 1030 nm, as obtained.
