Abstract: A direct-current gaseous optical maser comprises an elongated hollow cylinder that is open on both ends for defining a usable gas discharge path portion. A cathode and an anode are set back from the two ends within enclosures so that the gas discharge follows an approximately U-shaped path from the cathode through one open end of the cylinder and a similar path from the other open end to the anode.
