Via the high power optical fiber laser key point protection device, the melting point position of the optical fiber can be well protected.

Description

technical field [0001] The invention relates to a key point protection device of a high-power fiber laser, which belongs to the technical field of fiber lasers, and in particular relates to the field of high-power all-fiber lasers. [0002] technical background [0003] High-power all-fiber lasers have the advantages of good beam quality, high conversion efficiency, and high integration, and are widely used in industry and military fields. Modern industrial processing and military tactical weapons require the output power of fiber lasers to reach the kilowatt level or even 10,000 watt level. [0004] However, the production of kilowatt-level or higher-power fiber lasers requires breakthroughs in many core technologies, such as the preparation of high-power core devices, the protection of key hot spots, the protection of returning light, and photoelectric linkage control. Most of these technologies are foreign A few companies have mastered it, such as IPG, Rofin, SPI, etc. I...
