Abstract

The invention discloses a bi-directional mode-locked multi-state soliton fiber laser, belonging to the laser field, which comprises a pump source and a bi-directional ring resonant cavity formed by connecting a wavelength division multiplexer, a gain medium, a fiber chirped grating, an optical circulator, a polarization controller, an optical coupler and a saturable absorber. The pump source is used as the laser energy source and the gain medium is used to provide the gain for the generation of pulsed laser. The saturable absorber is used to realize the mode-locked operation of the laser. Thefiber chirped grating has two input reflection ports, which can compensate the positive dispersion and the negative dispersion respectively. The Optical circulator and optical coupler are used to couple fiber chirped grating to construct bidirectional transmission optical path with different dispersion distribution. With the help of polarization controller, the local polarization state of the laser can be changed, and the state of the mode-locked laser can be adjusted and switched. The bi-directional mode-locked multi-state soliton fiber laser of the invention can bidirectionally transmit andobtain mode-locked laser pulses respectively, and simultaneously provides multi-state soliton laser output.

Description

technical field [0001] The invention relates to the fields of fiber laser, ultrafast optics and nonlinear optics, especially the characteristics of bidirectional output of traditional solitons and dissipative solitons, and has potential scientific research in the fields of optical fiber communication, optical fiber sensing, optical logic systems, and laser physics research. The value and industrial applications, more specifically, relate to a bidirectionally mode-locked polystate soliton fiber laser. Background technique [0002] Fiber laser has flexible structure, convenient maintenance, no collimation, high conversion efficiency and excellent heat dissipation, and plays an important role in scientific research and industrial applications. With the help of passive mode-locking technology, fiber lasers can easily achieve femtosecond level (10 -15 second) ultrafast pulsed laser output, as a high-quality stable ultrafast pulsed light source, it is widely used in applications ...
