Abstract

This paper reports about a diagnostic system, which is used for monitoring the following quality characteristics of a high power CO₂-laser optic during its operating time: the grade of absorption, surface pollution and defects, the local refractive power, and the focal length. First the efficiency of the system is demonstrated by fundamental experiments with an off-line setup. Then a concept for the on-line application is described in order to use the sensor together with beam steering modules in a closed loop control of the laser beam.
