摘要：

The performance of an eye-safe laser based on a Er-doped orthovanadate (Er:YVO4) single crystal, diode-pumped at 976 nm (I-4(15/2) I-4(11/2) transition) and operating at 1603 nm (I-4(13/2) I-4(15/2) transition) with near diffraction limited beam quality is reported. A 10 mm long Er3+:YVO4 slab, cut with its c-axis perpendicular to the laser cavity axis, was pumped in sigma-polarisation and lased in -polarisation. The laser operated in a quasi-continuous wave regime with nearly 9 W output power, and with a slope efficiency of about 39% with respect to absorbed power. This is believed to be the highest efficiency and highest power achieved from an Er3+:YVO4 laser pumped in the 970-980 nm absorption band.
