Abstract

An all optical fiber dissipative soliton resonance mode-locked laser device is disclosed and belongs to the technical field of laser. The all optical fiber dissipative soliton resonance mode-locked laser device comprises a pumping source and an optical fiber annular cavity, wherein the optical fiber annular cavity are formed by connecting a wavelength division multiplexer, an ytterbium-doped optical fiber, an optical isolator, an optical fiber coupler, a polarization controller and an optical fiber non-linear annular reflecting mirror via optical fibers; the optical fiber non-linear annular reflecting mirror is formed by connecting two output ports of the optical fiber coupler via the polarization controller. The optical fiber laser device disclosed in the invention adopts an all optical fiber structure and is high in light beam quality, and the optical fiber laser device is convenient to weld and couple and can be maintained conveniently. The optical fiber laser device does not adopt any narrowband spectrum filter, and pulse splitting caused by narrowband filtering effects can be prevented.

Description

technical field [0001] The invention relates to the field of laser technology and provides an all-fiber dissipative soliton resonance mode-locked laser. Background technique [0002] Compared with traditional solid-state lasers, ultrafast mode-locked fiber lasers have the advantages of good beam quality, high gain, high efficiency, low threshold, tunable, compact structure, reliable operation, and good heat dissipation. In the past 20 years, ultrafast fiber lasers have been developed rapidly and have been widely used in optical communication, optical sensing, laser medical treatment, industrial processing, aerospace, material science, spectroscopy and nonlinear optics. Ultrafast fiber lasers are one of the active areas of optical research today. [0003] By artificially designing the dispersion characteristics in the cavity of the mode-locked fiber laser, ultrafast pulses with different parameters can be obtained respectively. When the intracavity net dispersion is negativ...
