Abstract

We demonstrate a compact, efficient Nd : Y V O 4 stable–unstable hybrid slab oscillator that was partially end pumped at 880 nm . A maximum output power of 165 W at 1064 nm was obtained with an optical-to-optical efficiency from absorbed pump power to laser output of up to 60% and a slope efficiency of up to 66%. The beam propagation factors M 2 were 1.7 in the stable direction and 1.4 in the unstable direction without sidelobes.
