Abstract : This invention relates to high energy chemical lasers and to a system for generating singlet data, energizing molecular gas for use with such lasers. More particularly, this invention concerns itself with an apparatus for generating molecular oxygen in the excited singlet-delta electronic state. In accordance with this invention, it has been found that molecular oxygen in the electronically excited singlet delta state can be generated in an efficient and reliable manner by a generating device which comprises a tubular reaction chamber having a substantially circular cross-section which in turn is positioned within a vacuum chamber. The generating device is then inter-connected to a conventional atomic iodine laser for providing the laser with electronically excited oxygen as one of the reacting components. The laser itself provides the necessary vacuum to evacuate the vacuum chamber of the generating device during its operation. A source of chloring gas is introduced into the center of one end of the reaction chamber along with liquid mixture of hydrogen peroxide and sodium hydroxide. Suitable control devices control the flow rates of the gas and liquid.
