Paper Abstract

Investigations have been carried out comparing thermal cutting using Nd:YAG and CO2 lasers. Analysis of the investigation results have led to conclusions concerning process efficiency, as referring to better absorption of laser radiation on metal-based materials at shorter wavelength behavior, as well as the influence of using an optical fiber for beam delivery on the processing results. The transmission properties of silica fibers with graded index and step index profile were investigated, when using a high power Nd:YAG laser. The beam parameters behind the two different fiber types related to the input parameters and the fiber geometry were theoretically and experimentally analyzed. The advantages and disadvantages for laser cutting with these fiber types are discussed with respect to physical properties and applicability.
