Optical fiber laser output device

Abstract

The invention relates to an optical fiber laser output device, which comprises: a light source generating mechanism, wherein the light source generating mechanism comprises a pumping source component,a pumping combiner, an optical fiber resonant cavity, a cladding power stripper and a collimating output device; a heat dissipation mechanism, wherein the heat dissipation mechanism comprises a firstradiator, a second radiator and a gas flow generating component; the pumping source component is mounted on the first radiator; the first radiator comprises a copper substrate, an aluminum substrateconnected with the copper substrate, and a plurality of heat pipes; the heat pipe comprises an evaporation section and a condensation section. The evaporation section of the heat pipe is welded on theupper surface of the copper substrate, and the condensation section of the heat pipe is welded on the upper surface of the aluminum substrate. The pumping source component is cooled by the first radiator. The heat pipe dissipates part of the heat on the copper substrate to the aluminum substrate through the first radiator. The gas flow generating component drives the gas between the first radiator and the second radiator to flow, so that the heat dissipation efficiency is ensured while the heat dissipation structure is simplified, the volume and the weight of the fiber laser output device areeffectively controlled, and the portability is improved.
