Abstract

A method for supplying a first gas and a second gas using a purge ring in a photonic processing system includes arranging a first layer and a second layer to define a first plenum and a first baffle, arranging the second layer and a third layer to define a second plenum and a second baffle, receiving a first gas at the first plenum that flows through the first plenum and the first baffle to an inner region, and receiving a second gas at the second plenum that flows through the second plenum and the second baffle to the inner region. The second baffle is one of less restrictive and more restrictive than the first baffle.
