摘要: We demonstrate a switchable, tunable and power-controllable dual-wavelength fiber laser in 2-μm region based on parallel cavities using 3 × 3 coupler. The topology is the connection of Bragg gratings (FBGs) coupler which act as two individual cavities, so that dual wavelengths are switchable by adjusting center FBGs cavity losses, respectively. With suitable losses input pumping power, we can obtain single- or laser. proposed configuration has very good application prospects fields atmospheric transmission, gas sensing, lidar new wavelength-division-multiplexed communication systems.
