Paper Abstract

A unique technology for the fabrication of high-quality and robust beam delivery optics for fiber lasers is presented. CO2 lasers are used to reshape the spherical surface of plano-convex fused-silica rod-lenses, and then fuse the optical fiber directly to these lenses. A specific fiber collimating system is presented and analyzed in terms of aberrations, insertion loss, M2, and return loss. Test results are compared to the theoretical modeling, demonstrating the accuracy and repeatability of this technology.
