A laser beam delivery system is presented, consisting of a high power Neodymium :YAG Diode Pumped Solid State DPSS laser, a complete vision processing system for seam tracking, custom electronics consisting of firmware developed especially for this application, processing head, integrated beam shaping optics and an all optical compact actuator to steer the high power laser beam to a target substrate. Delivery of <800W average power was successfully delivered to the target substrate with a homogenous rectangular beam profile. Beam steering resolutions of <3μm were achieved and target tracking accuracies were 50μm, limited by the vision system. Development of custom software was required to interpret system latency and vision system deviations encountered under production conditions. The system has been in serial manufacture since Dec2013.
