Description

technical field [0001] The invention relates to the field of laser technology and nonlinear optics, in particular to a mid-infrared supercontinuum fiber laser based on hybrid mode-locking technology. Background technique [0002] Mid-infrared supercontinuum light sources have broad application prospects in laser spectroscopy, environmental monitoring, biomedicine, lidar, material processing, optical communication systems and other fields. Fiber-based supercontinuum light sources in the near-mid-infrared band mostly use highly nonlinear fibers or highly nonlinear photonic crystal fibers as nonlinear media, but due to the high mid-infrared absorption of quartz glass materials, the wavelength cannot continue to extend to the long-wave direction. . In recent years, the development of non-silica glass optical fiber is relatively rapid, especially the fluoride optical fiber with low transmission loss, good environmental stability and high damage threshold has been commercialized,...
