The theoretical results show that by adjusting the insertion angle of a single F-P etalon, direct visible multi-wavelength laser output with different combinations can be achieved. Based on the guidance of theoretical parameters, we obtained maximum output powers of 729 mW, 420 mW, 382 mW, and 269 mW for single-wavelength at 639 nm, dual-wavelength at 604 nm&639 nm, 607 nm&639 nm, and triple-wavelength at 604 nm&607 nm&639 nm lasers, respectively, in the experiment. The experimental results agree well with the simulation. This method effectively simplifies the resonator structure and improves the conversion efficiency, providing a theoretical basis for guiding and optimizing the design of multi-wavelength laser. Such a visible multi-wavelength integrated laser source will have potential applications in fields such as laser medicine, color displays, and deep ultraviolet generation. 收起
