Abstract

High power DDL operating in the 445 nm region are rapidly evolving as one of the preferred laser technologies for welding, cutting, and engraving of highly reflective materials. Until recently, industrial blue laser sources have lacked the beam quality for performing remote processing of materials at the large working distances that are often preferred in many processes. In this paper we will demonstrate laser material processing results obtained with a new generation of industrial blue lasers with BPP of 1.4 mm*mrad. We will present results from remote laser processes including, conduction welding, keyhole welding, and engraving at long working distances.
