High-power fiber lasers are one of the most advanced and widely used technologies. They contribute to the creation of diverse, sophisticated, and beautiful parts. High-power fiber lasers are also used in industries such as mechanical design and manufacturing, home appliances, electronics, medicine, aerospace, defense, automotive, and many other fields. Ytterbium (Yb)-doped rare-earth active fibers are used as the main gain medium to create laser sources with powers >1000 W today. In this paper, the process of light wave propagation in high-power optical fibers is simulated. The intensity distribution of the single-mode fiber (SMF) is presented in 2D. Factors affecting laser power and beam quality M2 such as fiber length, core refractive index, core cladding, and pump source are analyzed.

摘要

High-power fiber lasers are one of the most advanced and widely used technologies. They contribute to the creation of diverse, sophisticated, and beautiful parts. High-power fiber lasers are also used in industries such as mechanical design and manufacturing, home appliances, electronics, medicine, aerospace, defense, automotive, and many other fields. Ytterbium (Yb)-doped rare-earth active fibers are used as the main gain medium to create laser sources with powers >1000 W today. In this paper, the process of light wave propagation in high-power optical fibers is simulated. The intensity distribution of the single-mode fiber (SMF) is presented in 2D. Factors affecting laser power and beam quality M2 such as fiber length, core refractive index, core cladding, and pump source are analyzed.
