US12601569 - Systems for projecting high voltage electrical discharges in air
The patent describes a system that utilizes a high-voltage electrical discharge device, specifically a Tesla coil, combined with a laser assembly to project high-voltage electrical discharges along laser-induced plasma filaments in air. This innovative setup allows for the controlled direction of electrical discharges through a specially designed firing cone that facilitates the interaction between the electrical discharge and the plasma filaments.
Claim 1
1 . A system for projecting high-voltage electrical discharge through air, comprising: a high-voltage electrical discharge device comprising a tesla coil having a hollow torus electrode; a firing cone constructed of electrically conductive material, the firing cone having a passage extending between opposite ends thereof, the firing cone is electrically connected to the hollow torus electrode and tapers from a wide end to a narrow end in a direction away from the hollow torus, the narrow end providing a breakout point for an electrical discharge from the hollow torus electrode, a laser assembly having at least one laser operable to produce electrically conductive laser-induced plasma filaments in air; wherein the at least one laser is disposed in the hollow torus electrode and arranged with a discharge end of the at least one laser aligned with the passage of the firing cone so that electrically conductive laser-induced plasma filaments produced by the at least one laser pass through the passage of the firing cone; and wherein when electrically conductive laser-induced plasma filaments pass through the passage of the firing cone, an electrical discharge at the breakout point is caused to travel along the electrically conductive laser-induced plasma filaments in air. a high-voltage electrical discharge device comprising a tesla coil having a hollow torus electrode; a firing cone constructed of electrically conductive material, the firing cone having a passage extending between opposite ends thereof, the firing cone is electrically connected to the hollow torus electrode and tapers from a wide end to a narrow end in a direction away from the hollow torus, the narrow end providing a breakout point for an electrical discharge from the hollow torus electrode, a laser assembly having at least one laser operable to produce electrically conductive laser-induced plasma filaments in air; wherein the at least one laser is disposed in the hollow torus electrode and arranged with a discharge end of the at least one laser aligned with the passage of the firing cone so that electrically conductive laser-induced plasma filaments produced by the at least one laser pass through the passage of the firing cone; and wherein when electrically conductive laser-induced plasma filaments pass through the passage of the firing cone, an electrical discharge at the breakout point is caused to travel along the electrically conductive laser-induced plasma filaments in air.
