Abstract : The patent describes a pulsed gas laser which uses continuously expanding gases that pass through the lasing chamber and subsequently generate a direct current, pulsed electric output which is fed back to stimulate laser emission. A conventional gas burner and nozzle assembly couple flowing gases into a standard laser cavity. Gases leaving the laser cavity pass between poles of an MHD magnet, generating output electric power which is transformed into high voltage pulses of output power. An alkali metal component is introduced into the system before the flowing gases reach the MHD magnet for increasing electrical conductivity of the gas therein and thereby enhancing large pulses of electrical energy feedback for stimulating additional laser action.
