Abstract

A Yb:YAG disk laser with V-shape stable resonator and active-mirror configuration, end-pumped by 940 nm InGaAs laser diode array, is demonstrated. Temperature dependence of output performances for the disk laser at low temperature is investigated. When the temperature of the crystal heat sink is turned to 133 K, the maximum output energy of 1.46 J per pulse at 1.03 μm wavelength operating at 10 Hz repetition rate is obtained, the corresponding optical-to-optical efficiency is 48.7%.
