The properties of Nd:YAG 946 nm and 473 nm laser were studied. By using Nd:YAG composite as laser gain medium, 11 W continuous-wave (CW) laser output at 946 nm was obtained under the incident pump power of 31.8 W, corresponding optical efficiency and slope efficiency were 34.6%and 35.4%, respectively. The M2 factor was 7.53 and the power stability was better than 0.4% with 0.5 h. After intra-cavity frequency-doubled by an LBO crystal which was cut for critical type I phase matching, 0.887 W CW output power at 473 nm was obtained, corresponding to an optical efficiency of 5.87%. Experimental results prove that the end pumped CW laser has important practical value.
