Abstract
A laser processing machine includes a measuring cell into which gas to be analyzed can flow, a means for decoupling diagnostic radiation from the laser radiation provided for material processing of a workpiece, and a sound detector for detecting the photo-acoustical effect produced in the measuring cell due to absorption of the diagnostic radiation by gas in the cell.
