摘要：

The theoretical research on the Yb: YAG laser pumped by the zero-phonon line with pumping wavelength of 969 nm is constructed, and the rate equations for this 969 nm pumped Yb: YAG laser are established. The optical-to-optical efficiency and the output laser intensity of this Yb: YAG slab laser amplifier pumped at 969 nm or 941 nm are obtained by numerical simulation under the same thermal load state. The simulation results show that the optical-to-optical efficiencies for both are almost equivalent. The pumping intensity for 969 nm pumping is 20% higher than that for 941 nm pumping. © 2019, Chinese Lasers Press. All right reserved.
