The invention provides a light source line width step-by-step compression system. A light source generation gain apparatus in a narrow line width light source generation apparatus generates a light source and transmits the light source as incident light to first optical fiber; the first optical fiber compresses the line width of the incident light based on a rayleigh scattering effect to obtain rayleigh scattering signals in an incident forward direction and an incident negative direction; one part of the rayleigh scattering signal, which is in the incident forward direction and transmitted to a first filter, is output while the other part of the rayleigh scattering signal is reflected back to the first optical fiber; the first optical fiber transmits the reflected back rayleigh scattering signal and the rayleigh scattering signal in the incident negative direction to the light source generation gain apparatus to be subjected to gain amplification; the gain-amplified rayleigh scattering signal is used as the incident light to be transmitted to the first optical fiber, so that the first optical fiber can perform cyclic compression on the line width of the incident light until the light source is completely output by the first filter; and the finally output light source is the narrow line width light source to be subjected to recompression. The light source line width step-by-step compression system is simple in structure, small in size and relatively low in cost.
Description
technical field [0001] The invention belongs to the field of light source generating devices, and in particular relates to a step-by-step compression system for line width of a light source. Background technique [0002] The single longitudinal mode laser beam with ultra-narrow linewidth is a high-quality light source with extremely low phase noise and ultra-long coherence length. with broadly application foreground. At present, there are many methods for forming ultra-narrow linewidth single longitudinal mode laser beams, such as short cavity method, saturable absorber, multi-ring ring cavity and other methods, but most of the lasers based on the aforementioned methods have complex structures, large volumes, and low The defects of high cost and unsatisfactory linewidth compression effect greatly limit the application of ultra-narrow linewidth single longitudinal mode laser beams.
