Abstract

A newly developed low-birefringence synthetic diamond is shown to be an effective intracavity heat spreader in Nd:YVO4 and Nd:GdVO4 disk lasers. A cw output power of 25.7W from only one double pass of the pump is reported. The diamond heat spreader is shown to increase the pump power density at which fracture occurs.
