    摘要： 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.
