The experimental results of continuous laser diode pumped Nd:YVO4 ring cavity configuration single frequency laser are reported.To reduce the influence of heat effect in laser,a new pump configuration is designed and better results are achieved.At room temperature,1064 nm single frequency laser with the power up to 9.9 W is obtained from pump power of 22.5 W.Optical-optical conversion efficiency is about 44.1%.Beam quality is M2x=1.14 and M2y=1.12.Frequency excursion is 83.7 MHz in one minute.Instability of output power is less than 0.5% in 7 h.
