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.

Method for detecting the operating condition of an optical element arranged along a propagation path of a laser beam of a machine for processing a material, system for carrying out said method and laser processing machine provided with said system
