Paper Abstract

The temperature field induced by thermal is investigated numerically with the laminar flow pattern in the direct-liquidcooled Nd:YLF thin disk laser, since it is one of the main reasons of deformation, strain and stress. The convective heat transfer coefficient on the two big surfaces of the disk is analyzed, which affects the temperature distribution directly. The convective heat transfer coefficient is no longer the thermal boundary condition but the analysis result in the analysis process. Moreover, the influences of coolant flow velocity, deposited heat power and channel thickness on temperature field are discussed. The simulation results reveal that the temperature and the cooling capacity of coolant vary on the pump power, flow velocity and channel thickness, which have a significant contribution to the temperature gradient in the disk gain medium.
