Abstract: | We report on the efficient continuous-wave (CW) dual-wavelength operation of a Nd:YVO4 laser at 1085 and 1342 nm. An output power of 1.72 W for the dual-wavelength was achieved at the incident pump power of 17.4 W. Intracavity sum-frequency mixing at 1085 and 1342 nm was then realized in a KTP crystal to reach the orange range. A maximum output power of 146 mW in the orange spectral range at 600 nm has been achieved. The orange output stability is better than 3.8%. The orange beam quality M 2 value is about 1.41 and 1.25 in both horizontal and vertical dimensions, respectively. |
