Paper Abstract

In order to compensate for the thermally induced lenses in high-power laser rods we investigate self-adaptive techniques based on thermo-optical processes. Recently we have demonstrated that the influence of the thermal lenses in high-power lasers can be reduced significantly by means of thin layers of either liquids or gels. After a short review of the past developments we discuss the limits of lasers with intra-cavity thermo-optically self-compensated amplifiers (TOSCA). It is shown that for Nd:YAG typically one compensating layer is needed for every 6 cm of rod length.
