Triggering and Guiding of High-voltage Tesla Coil Discharges by Femtosecond Laser-induced Plasma Filaments in Air

We report experimental guiding of high-voltage (HV) sparks discharges in air with plasma filaments generated by a terawatt femtosecond laser. Large sparks discharges are shoot up from a HV electrode fixed at the top of a Tesla coil voltage elevator to a farther grounded one. Ultrashort laser pulsed beams of energy on the order of the mJ through open air exhibit non-linear propagation effects. I...

Triggering and guiding megavolt discharges by use of laser-induced ionized filaments.

We have demonstrated the ability to trigger and guide high-voltage discharges with ionized filaments generated by femtosecond terawatt laser pulses. The plasma filaments extended over the whole gap, providing a direct ohmic connection between the electrodes. Laser-guided straight discharges have been observed for gaps of as much as 3.8 m at a high voltage reduced to 68% of the natural breakdown...
