Abstract

The invention provides a resonant mode-locked fiber laser based on 2Mum dissipative solitons. The resonant mode-locked fiber laser comprises a pumping source and an annular fiber cavity. The annular fiber cavity is formed by connection of a wavelength division multiplexer, a thulium-doped fiber, an optical isolator, a fiber coupler, a filter and a fiber nonlinear annular reflector through single-mode fibers. The fiber nonlinear annular reflector is formed by connecting two output ports of the fiber coupler through a fluoride (ZBLAN) ultra-flat dispersion compensation photonic crystal fiber. The resonant mode-locked fiber laser has the advantages that the fiber laser of an all-fiber structure has high beam quality, and is convenient for fusion and convenient to maintain; the fiber laser canoutput 2Mum dissipative soliton resonance pulses by adjusting pumping lights and characteristics of different parameters in the cavity.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a 2 μm dissipative soliton resonance mode-locked fiber laser. Background technique [0002] In recent years, 2 μm lasers have received a lot of attention due to their wide applications in spectroscopy, lidar, material processing, etc. Since thulium-doped fiber can be used as a gain medium, various 2μm fiber lasers such as high-power, mode-locked, Q-switched, wavelength-tunable, supercontinuum, etc. have been comprehensively studied in this field. More specifically, due to the large gain range of thulium-doped fibers, the 2 μm band also has great potential for future high-data-rate and high-capacity fiber optic communications. [0003] Due to the wide application of ultrashort pulse light sources in optical communication, optical sensing, nonlinear optics, industry and medicine, passive mode-locking technology as an ultrashort pulse light source has stimulated people's strong rese...
