  • Power supply for gas discharge lasers
    Patent number: 4648093
    Abstract: A high voltage power supply for energizing a gas discharge laser in either an enhanced pulse mode or a continuous mode, which power supply is simple to manufacture and minimizes the voltage that other parts of the energizing circuit are required to withstand. The voltage provided by a high voltage DC power supply is boosted by the interaction of first and second reactive components. A first reactance is provided which stores charges at the boosted potential. This charge is provided to the laser to initiate electrical breakdown. The second reactance generates a potential which is additive with respect to the potential provided by the high voltage DC power supply so that the first reactance is charged to a potential equal to the generated potential plus the potential of the high voltage power supply.

  • High power fundamental mode laser
    Patent number: 4500996
    Abstract: A high power, fundamental (TEMoo) mode gaseous laser is described having a discharge-confining bore tube which is provided with spaced-apart annular, inwardly-extending, radial projections or rings, which have inside diameters which match the fundamental mode diameter along the tube.
