Abstract: A condition or detecting a change in the condition of an optical element of a laser arrangement is detected. An ultrasonic signal is coupled into an optical element such that the ultrasonic signal travels along a path within the optical element, and a transit time or a change in transit time for the ultrasonic signal to travel along the path within the optical element is detected.

Abstract: Determination of the relative positioning of a laser machining beam and a process gas jet on a laser machine tool are accomplished by motion of detections made while moving the machining beam and gas jet in relation to a detection element. In some cases actions of the beam and gas jet themselves are detected, such as by cutting light response and sensor deflection caused by the gas jet. Relative head positions at the time of the deflections are used to calculate misalignment between the laser beam and gas jet.

Abstract: A laser processing machine for processing workpieces includes a beam guide containing a gas atmosphere, and also includes an apparatus for investigating the gas atmosphere in the beam guide for impurities. The investigation apparatus makes use of the photoacoustic effect. The measuring apparatus has a measuring chamber and at least one measuring head, where the beam guide acts as the measuring chamber. As a measuring chamber, the beam guide contains the gas atmosphere that is to be investigated and also a modulated laser beam modulated. The measuring head(s) are integrated into the beam guide and are used to detect the photoacoustic effect in the measuring chamber.
