Refractive Multi-Focus Optics for Material Processing

By Alexander Laskin Introduction Powerful multimode fiber lasers, as well as fiber‑coupled solid-state and diode lasers, are widely used in industrial laser applications, and beam shaping of these multi-kW sources is of great importance to improve technologies like welding, metal sheet cutting, cladding, hardening. Due to physical properties of light propagation in multimode fibers, these […]
