摘　　要：By analyzing the relation between the transmission of the output mirror and the output power in an intracavity frequency doubling laser,we choose an optimal transmission of the output mirror according to the laser application requirements.As a result,a high-power single-frequency laser at 540nm is obtained with a maximum output power of 8 W and a power stability of ±1% for three hours,whose beam quality M2 is better than 1.2.At the same time,a moderate FW power of 1.2 W is coupled out,which is enough to meet the requirements for local oscillation light and injected signal optical beams in quantum optics experiments.
