摘要：
Thermooptic effects often limit the power and beam quality of bulk-solid-state lasers. Cryogenically cooled (similar to 100 K) Yb:YAG lasers have been previously demonstrated to have relatively low thermooptic effects and high efficiency due to improved material properties at low temperatures. In this work, > 300-W average power with M-2 similar to 1.2 and 64% optical-optical efficiency has been demonstrated from an end-pumped-rod geometry power oscillator. To our knowledge, this is the highest average power to date from a cryogenically cooled Yb:YAG laser.
