Abstract

The invention discloses an optical fiber laser system for generating a soliton burst mode, and aims to solve the technical problem that an existing optical fiber laser is difficult to directly outputa burst mode soliton pulse. The system comprises a double-pulse bound soliton fiber laser (1), a fiber amplifier (2), a first fiber circulator (3), a first chirped fiber bragg grating (4), an opticaltime delay line (5), a phase modulator (6), a microwave source (7), a second fiber circulator (8) and a second chirped fiber bragg grating (9). The laser system realizes the output of the explosion mode soliton pulse, has the advantages of compact structure, low system cost, good stability and the like, can be directly applied to the field of micromachining, and can also be used as a seed source of a high-energy pulse amplifier.

Description

technical field [0001] The invention belongs to the technical field of lasers, and in particular relates to the design of a fiber laser system for generating soliton burst modes. Background technique [0002] Laser is one of the greatest inventions of mankind in the 20th century. With the development of society, it has become one of the most important tools in scientific research and industrial production. Among them, fiber lasers are widely used in spectroscopy, high-speed optical communication, combustion diagnosis, laser micromachining and other fields due to their advantages such as good beam quality, high peak power, compact structure, and maintenance-free. [0003] In the field of material processing, when the traditional high repetition rate laser pulse acts on the material, the target ablation point sublimates rapidly and takes away most of the heat, which makes the temperature of the sample drop, resulting in unsatisfactory ablation efficiency and effect. Therefore...
