Abstract

The invention provides an ultra-short pulse fiber laser. The ultra-short pulse fiber laser comprises a pumping source, an optical fiber coupler, a first reflection type optical fiber grating, a gain optical fiber, a second reflection type optical fiber grating and an acousto-optic modulator; the pumping source is connected with the input port of the optical fiber coupler; the output port of the optical fiber coupler is connected with the first reflection type optical fiber grating; the first reflection type optical fiber grating is connected with the acousto-optic modulator through the gain optical fiber; light is output through the second reflection type optical fiber grating; the pumping source, the optical fiber coupler, the reflection type optical fiber gratings, the gain optical fiber and the acousto-optic modulator are respectively arranged on a substrate; the substrate is provided with parallel heat dissipation channels; and the heat dissipation channels form a heat dissipation array. The ultra-short pulse fiber laser of the invention can satisfy requirements for high integration, high average output power and high peak power and can also assist in reducing cost. According to the ultra-short pulse fiber laser, an all-optical fiber structure can be realized. The ultra-short pulse fiber laser has the advantages of simple design and compact structure.

Description

technical field [0001] The invention relates to the technical field of fiber laser, in particular, the invention relates to an ultrashort pulse fiber laser. Background technique [0002] Fiber lasers have the advantages of small size, light weight, high conversion efficiency, and good output beam quality, and have been developed rapidly in recent years. Pulsed lasers with high output power, high beam quality, and high stability are one of the hotspots in the laser field, especially Q-switched and mode-locked fiber lasers, which can generate high-frequency ultrashort pulses and are widely used in optical communication systems, optoelectronics, etc. There are broad prospects in many fields such as sensing, detection and diagnosis, biomedicine, precision micromachining and military affairs. [0003] According to the principle of generating optical pulse sequences, pulsed fiber lasers can be divided into two types: Q-switching (Q-Switching) and mode-locking. The repetition fre...
