Laserobot: optical and technological characterization

In this paper we describe the results of a complete laserobot characterization. The laser system considered consists of a 5.0 kW CO2 laser source and an anthropomorphic robot with an internal path for the beam. The focused laser beam diameter, the best focus position, the beam quality factor M2 was compared, in regards to two laser output windows and two kinds of mirrors inside the robot. The influence of the beam parameters, obtained in the different conditions, on the laser process has been analyzed considering penetration tests on steel sheets.
