  • Publication number: 20250162066
    Abstract: A laser processing method may comprise: a) directing a laser beam onto the work piece at a processing zone of the work piece for executing a laser processing; b) executing a relative movement between the laser beam and the work piece; c) acquiring optical signals, more preferentially a plurality of acquired images, from the processing zone; d) determining a time course of one or more characteristic parameters obtained starting from the optical signals, more preferentially from the plurality of acquired images; e) estimating in dependence of each time course of the one or more characteristic parameters a roughness obtained during the laser processing. During the step e) at least one respective statistical parameter is determined from the time course of the one or more characteristic parameters and afterwards a continuous estimate in real time of the roughness is calculated in function of each determined statistical parameter.

  • Patent number: 11685002
    Abstract: A method and system for detecting an operating condition of an optical element along a propagation path of a power laser beam in a laser processing machine head are based on a first signal of a back-propagating optical radiation at the wavelength of the laser beam; a second signal of a back-propagating optical radiation having a wavelength in the near infrared; a third signal of an optical radiation emitted by the optical element in the infrared in proximity to its surface; a fourth signal which is a function of the time-of-flight of an acoustic wave launched through the volume of the optical element.
