  • Velocity selected laser ablation metal atom source
    Patent number: 5567935
    Abstract: A pulsed plume of laser ablated photo-ionizable material is emitted from a target in a vacuum, and a pulsed beam of light thereafter produces ionization of two plume sections straddling a central nonionized plume portion. A mask is provided, intermediate the plume and the laser generating the ionizing pulsed beam of light, to shield the central plume portion to prevent ionization thereof. The ionized portions of the plume are swept away from the vicinity of the non-ionized plume portion by a magnetic field, and the remaining nonionized portion passes through an aperture in a retrieval mask to produce the output of the atomic source.

  • Condensed phase exciplex lasers
    Patent number: 5134625
    Abstract: The invention provides a laser medium having improved photodynamical properties. The medium includes the condensed phase, namely solid or liquid phase, of a mixture of one or more rare gases and a halogen donor. The gases are first combined and then condensed to form the laser medium. A solid state rare gas crystal laser is also provided.
