With the development of laser technology, the demand for the smart, miniaturized and stable optics of optical devices is getting higher and higher. A tunable dual-wavelength micro-nano-fiber laser is proposed. The laser is based on the micro-nano fiber as the basic component to improve the performance and mechanical toughness of the whole device. The mode of operation depends on the ring resonator structure to increase the output power and prolong the length of the gain medium; and the tunable dual wavelength micro-nano According to the coupling principle of parallel micro-nano fibers, the characteristics and working flow of single-ring resonator and double-ring resonator are analyzed. The experimental results show that the central wavelength of the pump light emitted by the laser is more stable, the power of the pump laser is effectively increased, and the laser beam with more stable oscillation is obtained.
