Abstract
A Yb:YAG disk laser with V-shaped stable resonator and active-mirror
configuration, end-pumped by a 940-nm InGaAs laser diode array, is demonstrated.
Performances and optimization of the disk laser at low temperature over a range of
130-200 K are investigated theoretically and experimentally. Laser output energy of
1.46 J/pulse operating at 10-Hz repetition rate is obtained with the optimum output
coupler transmission of 30%, and the corresponding optical-to-optical efficiency is
48.7%.
