We report a new, to the best of our knowledge, record power and efficiency for a 946 nm NdYAG laser, producing 110W (5TWm-2sr-1) with a slope efficiency of 80%, with respect to absorbed pump power, and an optical-to-optical efficiency of 74%, with respect to incident power. To achieve this performance, we utilized a closed-cycle acoustic Stirling cryostat to maintain the gain medium temperature at ∼80K and direct in-band pumping with a volume-Bragg-grating stabilized diode laser bar operating at 868 nm. Daily operation, including cycling of t
