Method for making chemical laser nozzle arrays

摘要

A method for making chemical laser nozzle arrays in which individual mandrels are molded of plastic material in the shape of the nozzle openings. The mandrels are secured with the mouth end attached to a base plate. Metal is electrodeposited on the base plate to a thickness in excess of the length the mandrels project above the base plate. The surface of the deposited metal is ground down to expose the throat ends of the nozzle-forming mandrels. The deposited metal is separated from the base plate and the arbors removed to provide an array of nozzle openings in the deposited metal.
