technical field [0001] The invention relates to a low-jitter and high-repetition-frequency supercontinuum light source, which belongs to the technical field of lasers. The invention can be applied to many fields such as space laser communication, biomedical imaging, and spectroscopy. Background technique [0002] Since the discovery of the supercontinuum phenomenon in optical fibers, due to its rich spectral components and coherent properties, supercontinuum has been widely used in communication, biological imaging, spectroscopy and other fields. Traditional supercontinuum light sources exhibit very severe pulse jitter due to nonlinear effects such as modulation instability in optical fibers, which severely limits many methods based on fast kinetics and non-repetitive measurements, such as single-pulse spectroscopy and microscopy. application. Using pulse triggering to control modulation instability in fiber is an effective method to obtain low-jitter supercontinuum. [0...
