✦ Synopsis

The thermal effects of the diode end-pumped Nd:YVO 4 slab laser crystal are investigated both analytically and numerically. The theoretical model is established with considering the divergence of the pump beam in the slab. A detailed theoretical analysis of the temperature, stress and the focal length of thermal lens are presented. Using 3D finite element analysis, an accurate numerical solution based on the theoretical model is achieved. Our analysis includes the thermal fracture damage of the thermally and optically anisotropic slab and the predicated values are compared with the experimental results.

High efficient CW lasers at 1064 nm and 1342 nm were realized in a compact diode-end-pumped Nd:YVO4 slab. The maximum 1064 nm output power of 22.5 W was obtained under the pump power of 56.0 W, corresponding to the maximum optical conversion efficiency and slop efficiency of 40.1% and 50.1%, respect
