Laser system technology for an improved workpiece tracking in 3D CO2 laser beam cutting

The integration of adaptive optics into the working head of a carbon-dioxide laser machine allows the variable adjustment of the focus position in relation to the workpiece. The parallel gas flow produced by Laval nozzles allows the laser cutting with a nozzle distance of up to 15 mm. A new method for laser cutting of three dimensional workpieces is possible by a specially designed working head with adaptive optics and Laval nozzles.
