Abstract
Thermal effects can be exploited to generate adaptive optical devices which compensate for thermal lenses in solid-state lasers. The thermooptically self-compensating amplifier (TOSCA), consisting of a liquid layer sandwiched between two laser rods, is a very promising concept due to its simple and compact design. We present the application of the TOSCA scheme in a dual-head Nd:YAG laser producing an output power of more than 300W.
