  • Patent number: 11794283
    Abstract: A unitary adapter for attaching a cutting nozzle to a laser cutting head includes an inner cylinder made of ceramic, a conductive shield sintered to the outer sidewall of the ceramic cylinder, a threaded conductive holder (for accepting the cutting nozzle) mounted in an opening at one end of the ceramic cylinder, and a coaxial connector (for connection to external measuring equipment) attached to an opposite end of the ceramic cylinder. A pair of wires is formed to be embedded within the ceramic material and provide separate electrical connections between the coaxial connector and: (1) the threaded holder, and (2) the conductive shield. The various components are sintered to the ceramic body to form permanent attachments, creating a unitary structure less susceptible to the high levels of acceleration and elevated temperatures associated with the laser cutting process.

  • Publication number: 20220234138
    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.

  • Patent number: 11112615
    Abstract: The invention relates to a device and a method for generating a multiple spot during laser material processing. According to the present invention, the power distribution is selected by pushing at least a first mirror into the laser beam. The light beam always falls on only one side of the mirror, so that the mirror can be produced easily and economically.
