To obtain an efficient and stable single-frequency green laser source, up to 100% output from the incident fundamental power to the second harmonic output is proposed by placing a booster within an extremely resonant doubler. A 0.5 W Nd-YAG NPRO was used as the master laser. The simulation assumed three parameters, namely, that the coupling efficiency of the pump is 65%, that the transmission efficiency at SHG is 75%, and that the passive loss of the resonator is 0.2%. It was found that the threshold of parasitic oscillation can be increased by introducing a directional loss within the resonator.
