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.
In this paper, a thin disk multi-pass amplification system is designed based on the conjugated double parabolic mirror pumping thin disk laser module, which realizes 20 passes transmitting through the thin disk crystal. The light transmission matrix is used to optimize optical mode matching of seed laser spot size and pumping spot size during the multi-pass transmission. At the same time, anti-misalignment stability of the thin disk multi-pass amplification system and the aberration of output laser beam are analyzed in deeply.
