  • Tubular singlet delta oxygen generator
    Patent number: 4558451
    Abstract: A generating device for producing a laser energizing gas in the singlet delta, electronic state comprising a vacuum chamber; a tubular reaction chamber positioned within said vacuum chamber, said reaction chamber having a closed end and an oppositely disposed open end; means positioned in said closed end for introducing a flow of a gaseous reactant into said reaction chamber; means positioned adjacent said closed end at an angle perpendicular to the position of said gas introducing means for introducing a stream of a liquid reactant into said gas flow to effect a chemical reaction therebetween and the generation of a laser energizing, singlet delta gas; and means for interconnection to a lasing device for directing a flow of said generated, singlet delta gas to a lasing cavity.

  • Method and apparatus for iodine vaporization
    Patent number: 4434492
    Abstract: Iodine vapor is supplied to an oxygen iodine laser by an improved iodine vaporizer. The vaporizer has a radiation transparent window and iodine crystals are contained in the vaporizer. Broad beam radiation from a variable intensity source is directed through the window into the vaporizer where it is absorbed by the iodine crystals, causing the iodine crystals to sublime. The iodine vapor is transported to the laser by a carrier gas flowed through the vaporizer. Coarse control of the iodine flow is achieved by controlling the carrier gas flow. Control of the amount of iodine vapor introduced into the carrier gas flow is achieved by varying the amount of radiation directed into the vaporizer.

  • Continuous wave chemically pumped atomic iodine laser
    Patent number: 4267526
    Abstract: CW laser action achieved on the .sup.2P 178-.sup.2P 3/2 transition of the iodine atom by energy transfer from the .sup.1 .DELTA. metastable state of O.sub.2. The effluent from a conventional oxygen generator was mixed with molecular iodine at the entrance of a longitudinal flow laser cavity where the I.sub.2 was dissociated by a small amount of O.sub.2 (.sup.1 .SIGMA.) that was present in the flow due to energy pooling processes. The measured output power was greater than 4mW.
