Abstract

The invention provides a high-flat C+L band broadband light source system with single-end pump spectrum compensation, which includes a pump source, a first wavelength division multiplexer, a first erbium-doped optical fiber, a coupler, and a connecting The second erbium-doped optical fiber and the second wavelength division multiplexer to the first output of the coupler, the loop mirror connected to the second wavelength division multiplexer, and the first wavelength division multiplexer connected to the The isolator of the device, wherein the second output of the coupler is connected to the second wavelength division multiplexer, the length of the first erbium-doped fiber and the second erbium-doped fiber are different but the doping concentration is the same, The power of the first output of the coupler is smaller than the power of the second output. The high-flat C+L band broadband light source with single-end pumping spectrum compensation of the present invention has simple structure, low cost, and can obtain an ASE light source with high flat light output, which has important theoretical significance and application value.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a high flat C+L band broadband light source with single-end pumping spectrum compensation. Background technique [0002] As a laser light source with broad application prospects, fiber laser has the advantages of broadband tunability, high signal-to-noise ratio, and narrow output laser linewidth. It can be widely used in optical fiber sensing, optical fiber communication, optical processing, etc. field. Fiber laser consists of three parts: pump source, resonant cavity and gain medium. [0003] At present, the amplified spontaneous emission light source (Amplified Spontaneous Emission, ASE) has the advantages of high flatness, wide output spectrum, high output power, long service life, etc., and is widely used in optical communication, optical fiber sensing, optical device testing and other fields. . Most of the broadband light sources currently on the market are superluminescent light-em...
