Abstract: A light source apparatus for producing intense monochromatic light from a low-temperature plasma is disclosed. The light source apparatus comprises a housing member for confining a gas at subatmospheric pressure, the housing containing output means disposed to transmit light from the confined gas. At least one anode and one cathode are positioned within the gas in electrical circuit relationship with each other. First control means are provided for controlling the voltage applied to the anode and second control means independently control the temperature of the cathode by regulating the power supplied to it. The pressure of the gas is controlled by a third control means. An intense monochromatic light output is achieved by confining the gas in said chamber at a controlled predetermined reduced pressure, independently controlling the temperature of the electron emitting cathode by means of said second control means and applying a predetermined controlled low voltage to said anode by said first control means. An intermediate mode current is drawn from said cathode and produces in the confined gas a region having a high density of metastable atomic states. A lowtemperature, high-density plasma is continuously produced in said region and intense monochromatic light is emitted as a result of the recombination of ions and electrons in said plasma.

Abstract: 957,921. Electric discharge lamps. GENERAL ELECTRIC CO. Nov. 24, 1961 [Dec. 27, 1960], No. 42095/61. Heading H1D. [Also in Division F4] An illuminating device comprises an enclosure having a transparent wall and means for holding in the enclosure a lamp containing a vaporizable substance, the temperature of the lamp being controlled by a heat-conducting device which extends from the interior of the lamp to the exterior, and is so arranged that its inner end contacts for heat conduction a restricted area of the lamp and its projection extending outside of the enclosure serves for heat dissipation. In one form, a part 5 of a lamp 3 is contacted by a tubular container 4 which extends upwardly to the outside of the enclosure 1 and which contains a vaporizable liquid and a non-condensable gas, and in operation, the liquid is co-operated, the vapour condensed in a copper condenser 9 and the liquid returned to the lower part of the device. Alternatively, two hollow tubes may be used, one inside the other, and the vapour forced up the inside of the smaller tube to be condensed on a heat-dissipating surface preferably cooled with cooling fins, and the condensed liquid returned between the two tubes. In either case, the outside tube may be lagged with material 20, and a heat-conducting grease used between the lamp and the heat-conducting device. Specifications 472,307 and 821,321 are referred to.
