Abstract
A long pulse, fast flow laser system and method in which a laser having a gas inlet and a gas outlet and electrical discharge electrodes has its inlet connected through a valve to a source of laser gas and its outlet connected to a vacuum. A control circuit opens the valve upon a request for laser firing. The valve permits the laser gas to flow through the laser to the vacuum at high speed. A high-voltage power supply is triggered, creating an electrical discharge across the electrodes. After the end of the laser pulse, the valve is shut to cut off the flow of laser gas and the vacuum is reconstituted.
