We utilize two different experiment structures of V-shape cavity and linear cavity to realize high-power laser output at 671 nm. The nonlinear crystal LBO is used to convert 1342 nm to a red light of 671 nm through second harmonic generation in laser resonator. The experimental results show that the output power is up to 4.05 W at incident pump power of 22.9 W with V-cavity setup. Furthermore, we simplify the structure, the output power is up to 5.22 W at incident pump power of 22.5 W with linear cavity setup.
