Cladding power stripper adopting graphite and white graphite materials and micro-channel water cooling

Abstract

The invention discloses a cladding power stripper adopting graphite and white graphite materials and micro-channel water cooling. The cladding power stripper comprises a heat sink protection shell, a heat sink, a high-refractive index glue cavity and an optical fiber; the optical fiber is arranged in the center of the interior of the high-refractive index glue cavity; the high-refractive index glue cavity is coated with the heat sink; the heat sink is made of the graphite material; a micro-channel is arranged on the surface, close to the high-refractive index glue cavity, in the heat sink; the heat sink protection shell wraps the heat sink; and cooling fins are arranged under the bottom of the heat sink protection shell and are made of the white graphite. According to the cladding power stripper, the graphite is used as the heat sink material, the white graphite is used as the material of the cooling fins at the bottom of the heat sink shell; and a micro-channel water cooling technology with reasonable micro-channel diameter and shape is applied to the cladding power stripper, so that the temperature of the stripper can be reduced, efficient heat dissipation is realized, and uniform internal heat distribution is ensured.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of fiber laser devices, in particular to a cladding power stripper using graphite, white graphite materials and microchannel water cooling. Background technique [0002] Cladding Power Stripper, CPS is a very important device in the fiber laser system. It can not only absorb the cladding light in the double-clad fiber, but also ensure the good transmission of signal light in the fiber core. As the output power of the fiber laser increases to tens of thousands of watts, the optical power of the cladding in the inner cladding of the fiber also increases to the order of kilowatts. Thousands of watts of cladding light converts extremely high heat in the stripper, and if it is not handled properly, it will pose a great threat to the stability of the entire laser system; while the thermal management technology of traditional cladding power strippers is stable for high-power fiber lasers for a l...
