We have demonstrated a quantum-defect-limited operation in a diode-pumped Yb:YAG oscillator at low temperature. The highest slope efficiency of 90% at the crystal temperature of 70 K was obtained, which was close to the quantum efficiency of 91.2%. An optical-to-optical efficiency and a laser gain were 74% and 8 cm-1, respectively at a low pump intensity of 2.3 kW/cm2.
