研制了一种由激光二极管阵列端面泵浦的Nd∶YVO₄晶体腔内双波长和频连续波大功率橙黄光激光器。利用I类临界相位匹配LBO,由1 064 nm和1 342 nm内腔和频获得了593 nm橙黄激光。在12 W注入泵浦功率下,获得了1.1 W的TEM₀₀模和低噪声橙黄激光输出,光光转换效率为9.2%,M_{2因子<1.2,4 h功率不稳定度<±2%。该输出功率是目前腔内和频593 nmNd∶YVO4激光器中最高的。}

A laser diode array end pumped high power orange yellow continuous wave Nd :YVO₄dual-wavelength laser with intracavity sum-frequency mixing was demonstrated.By type I Critical Phase Matching (CPM) LBO,593 nm orange-yellow laser is obtained using 1 064 nm and 1 342 nm intracavity sum-frequency mixing.With 12 W incident pump laser,1.1 W TEM₀₀ mode orange-yellow laser output with low noise is obtained,the optical-to-optical conversion goes up to 9.2 %,the M_{2 factor is less than 1.2,and the power instability is less than±2 % within 4 h.This is the highest output power achieved at 593 nm with an intracavity sum-frequency Nd∶YVO4 laser.}
