摘要：

Highly efficient continuous-wave laser oscillation in Yb:YAG microchip crystal has been realized at room temperature by high intensity Ti:sapphire laser pumping. The maximum output power of 810mW was obtained at 1048 nm wavelength oscillation. The optical-to-optical efficiency was 81% for the incident pump power and 85% for the absorbed pump power. These optical-to-optical efficiencies are close to the quantum-defect-limit of 90%.
