| Abstract: | The thermal effects such as the temperature distribution, temperature gradient, and the thermal lensing effect inside all-solid-state miniature Yb:YAG laser are investigated under the lasing and non-lasing conditions by using mid-infrared camera and interferomence measurement technology. The characteristic parameters of Yb:YAG laser are optimized according to the thermal effect. Output characteristics of the laser are studied for different doping concentrations. The laser output power is 1.7 W, the slope efficiency and opt-optical efficiency are 26.2% and 13.5%, respectively, for 2.3% doping. For 5.0% doping concentration the laser output power of 2.8 W with the slope efficiency of 51% and opt-optical efficiency of 24% are obtained. |
