Cryogenic experts at the NASA Glenn Research Center will develop models to explore mixtures and pressures of cryogens and gases and how they would react with a warm submarine.
With pressure and electricity, the laser creates dimers by passing electrical current through mixtures of reactive gases, such as fluorine or chlorine, and inert gases, such as krypton or argon.
