We report cw single-mode output at 1.34 μm in a Nd:YVO4 microchip laser pumped separately with a Ti:sapphire laser and a diode laser in the region of 809 nm. The 0.5 mm × 1.0 mm × 1.0 mm Nd3+-doped YVO4 crystal produced output powers as high as 60 mW with slope efficiencies as high as 40% and laser thresholds between 155 and 275 mW by use of a pumped volume of approximately 150-μm diameter and 0.5-mm length. Data are also presented for the laser’s performance as a function of pump wavelength and for the spectral variation of the output with crystal temperature.
