Optimum design for Yb:YAG disk laser with zero thermal load

A theoretical thermal load model is built to optimize the operation of the Yb:YAG disk laser with zero thermal load. The influences of the number of pump passes and thickness of gain medium on the absorption efficient, optical-to-optical efficiency and input pump power intensity are investigated in detail. And the optimal number of pump passes and thickness of gain medium are delivered based on the model.
