  • Publication number: 20240426654
    Abstract: The disclosure relates to a system and method for monitoring a high power laser beam in a laser material processing optical system, and provides a device and method for monitoring a high power laser beam. According to the present disclosure a detailed determination of properties of a high-power laser beam takes place in the direction of an optical fiber or laser beam entering a laser processing head connected to the laser source and these measurements can be performed during the processing operation. The device according to the present disclosure has optical sensors for measuring the intensity and respective current laser power.

  • Patent number: 12103105
    Abstract: A laser cutting head uses a nozzle and gas flow to perform laser cutting or the like. The laser processing and the gas flow passes from an end of the housing. A sensor assembly affixed to the end of the housing has a first through which the laser processing passes and an orifice from which the gas flow passes. A conductive adapter affixes to the sensor assembly and has a passage through which the laser processing passes. The nozzle affixes in a receptacle in an end of the conductive adapter. A collar disposed about the adapter defining one or more gas flow passages therethrough. A cover is disposed between the sensor assembly and the collar and encloses a space communicating the gas flow from the orifice to the one or more flow passages of the collar.

  • Publication number: 20240082961
    Abstract: The disclosure relates to a system and a method for monitoring the state of optical elements of a device for laser material processing. According to the present disclosure a detailed monitoring of the state of optical elements of a device for laser material processing takes place by monitoring properties of laser radiation in the direction of an optical fiber or laser radiation entering a laser processing head connected to the laser source and these measurements, which can be performed during the processing process. The device according to the present disclosure has optical sensors for measuring the intensity and respective current laser power.

  • Publication number: 20230095918
    Abstract: A laser processing head for directing a laser beam includes two reflectors and a sole lens element. The first reflector disposed in a housing's interior reflects the laser beam from a source to the second reflector, which then reflects the laser beam toward a process zone for a workpiece. The single lens element is disposed in the housing's interior between the reflectors. The lens element can be moved to adjust a focal position of the laser beam beyond the housing's outlet. To reduce contamination, one or more nozzles are configured to direct purge gas across one or more of the first reflector, the second reflector, and the lens element, while one or more collection areas disposed in the interior are configured to collect contamination directed from the purge gas.
