FIELD: process engineering.
SUBSTANCE: invention can be used in aircraft engineering. Adapter for working head of the device intended for making holes by laser beam comprises beam focusing appliance, mirror and device to feed auxiliary medium for laser beam. Said adapter has first laser beam inlet hole and second pulse laser beam outlet hole. Beam focusing appliance is arranged ahead of second pulse laser beam outlet hole. Mirror is arranged on laser beam optical path behind said focusing appliance so that outlet beam forms with inlet beam the angle smaller than 180°. Device to feed auxiliary medium for laser beam allows said medium to pass through said second hole along laser beam direction.
EFFECT: higher accuracy of holes produced by laser beam.
