Abstract

The use of adaptive optics in the beam delivery system of CO₂ laser machines is known as a powerful method to optimize the processing results. Focus radius and position can be controlled independently of one another by the appropriate choice of the adaptive optics focal lengths. The improvement of the processing results by the compensation of varying beam path lengths is discussed for CO₂ laser beam cutting. A new method for the automatic adjustment of focus parameters to the demands of the process is shown for the examples of cutting mild steels and stainless steels.
