A dual-wave Quasi-CW Nd:YAG laser has been demonstrated at the wavelengths of 1319nm and 660nm. The radiation energy level of the 1319nm transition was analyzed. The critical technology of restraining resonance of 1064nm so as to improve that of 660nm was discussed. Sophisticated optical coating and cavity structure was studied. And a maximum CW Output power of 43W at1319nm was acquired. Based 1319nm laser, a intracavity frequency-doubling laser of 660nm was also demonstrated by using KTP crystal and a acousto-optically Q-switch. And a Quasi-CW red light output power of 2W at 660nm was acquired, accordingly, dual-wave output was realized.
