A technique of constructing a plurality of holes in sheet material by scanning a coherent laser beam across holes in a mask overlaying said material. The use of a stream of gas coaxially aligned with said coherent light beam is also disclosed. A special technique is included for making one or more holes in a non-homogeneous particulate sheet material having finely divided particles held together by a binder, such as green (unbaked) ceramic, with the use of a coaxial coherent light beam and gas pressure stream.
