1.1 W内腔和频连续波橙黄光Nd:YVO4激光器

摘要

A laser diode array end pumped high power orange yellow continuous wave Nd:YVO4 dual-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 M2 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.%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%,M2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.
