Abstract

In radiation balanced lasers, anti-Stokes fluorescence is used to minimize the heat generated by the quantum defect and other non-radiative processes. Thermo-optics distortions can be minimized, enabling the scaling to high power. Here, experimental results of radiation balanced operation in various disk gain materials (i.e. YLF:Yb and LLF:Yb ) are presented. Different multipass pumping schemes are investigated for pump beam area scaling towards high power CW operation. Laser cavity design and thermal management issues are also discussed.
