A laser gain fiber cooling device

Abstract

Provided is a laser gain optical fiber cool device which can realize high-efficiency heat dissipation of high-thermal power density optical fiber, so that a significant heat dissipation effect is achieve, As that high power output of the fib laser is provided with strong support, By using a combination of multiple sub-components, Each sub-component has an independent cooling liquid circulating channel, which dissipates heat independently, and can effectively prevent the accumulation of heat in the cooling liquid flowing process and the occurrence of overheating at one end of the optical fiber,thereby preventing the optical fiber end effect, damaging the optical fiber, and effectively reducing the probability of the optical fiber being burned out due to the local overheating.
