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