Investigation of single mode high-power fiber laser used in industrial metal cutting machines

Abstract

High-power fiber lasers have demonstrated great potential in various industries such as industrial, medical, aerospace, defense, and many others. Utilizing single-mode fiber configuration offers advantages such as good beam quality, high power, stability, and efficiency. Therefore, high-power single-mode fiber lasers are applied in the manufacturing and processing of fine details. Ytterbium-doped active fibers are primarily used as the amplification medium, generating laser sources with powers exceeding 200 W. The objective of this paper is to simulate the intensity distribution of single-mode fiber, analyze parameters affecting the output power of high-power fiber lasers, such as refractive index, core diameter, fiber length, pump scheme, and beam quality (M2). This aims to select optimal characteristics for single-mode fiber in specialized metal cutting laser machine applications.
