[Abstract]:An orange-red laser with tunable wavelength and CW output is designed and fabricated based on the compound cavity structure. The laser is a resonant cavity with p-polarization 1 062.9nm fundamental frequency light produced by side-pumped Nd:GdVO_4 crystal and periodic polarization crystal MgO:PPLN (three polarization periods are 29.0 渭 m, 29.0 渭 m). The single resonance optical parametric oscillator (OPO) is composed of 29.8 渭 m and 30.8 渭 m. In the overlapping region of two resonators, the intracavity sum frequency of the s-polarized signal light and the p-polarized 1 062.9nm fundamental frequency light is carried out by using the type 鈪，
