Abstract
A gas replenishment system for a gas laser utilizes a gas metering device between a gas reservoir and the gas laser tube which operates at a pressure below the gas reservoir pressure. The metering device incorporates a body of gas entrapping material. The tube pressure is detected and when low an electrically controlled valve is energized for a predetermined time which allows gas to flow from the reservoir, into the gas entrapping material and from there to the tube. If the tube pressure is not restored to its proper level, the system recycles for another equivalent period of time.
