A temperature-modulatable optical fiber water cooling plate and optical fiber laser

Abstract

The invention provides a temperature-modulatable optical fiber water-cooled disk and an optical fiber laser, comprises a substrate, a plurality of isolation grooves extending radially to the side of the substrate are arranged in the inner of the central position on the substrate, a temperature modulation region is formed between each adjacent two isolation grooves, water cooling pipes are arrangedin each temperature modulation region, and water inlets and outlets communicated with the two ends of the corresponding water cooling pipes are arranged at the side of each temperature modulation region. By providing a plurality of radial distribution isolation grooves on the front surface of the substrate, such that the substrate is divided into a plurality of temperature modulation regions, thewater cooling pipes in each temperature modulation zone are connected with water coolers with different temperatures, The fiber temperature can be modulated periodically and gradient when the fiber is coiled on the substrate in different ways. At the same time, the fiber temperature modulation is realized by a single substrate, which simplifies the structure of the fiber laser system in the temperature modulation process of the fiber. The invention is applied to the field of optical fiber temperature modulation.

Description

technical field [0001] The invention relates to a water-cooled plate and a fiber laser, in particular to a temperature-modulating fiber water-cooled plate and a fiber laser. Background technique [0002] Studies have shown that temperature modulation of the fiber temperature of the fiber laser can achieve the effect of suppressing mode instability and suppressing nonlinear effects. At present, the method of realizing the temperature modulation of the fiber in the fiber laser is to use multiple water-cooled plates to modulate the temperature of each part of the fiber respectively. As a result, the temperature of the fiber in this part cannot be well controlled, which is not conducive to the stability and safety of the high-power fiber laser.
