摘要

We report a low-noise continous-wave single-frequency Nd:YVO4 laser at 1.06μm directly pumped by an 880-nm laser diode.A maximum output power of 22 W is achieved with an optical-to-optical conversion efficiency of 46.3％.The stability of the output is better than ±0.7％ in the given four hours.The output beam is almost diffraction-Iimited with a measured beam quality of M2x =1.05 and M2y =1.02.The intensity noise and the phase noise of the laser reach the shot-noise limit at an analysis frequency of 5 MHz.
