Abstract: Method of producing a plasma conductor in air with the aid of a femtosecond high-frequency pulsing and high-repetition rate laser. The plasma is used for transmitting a current between an electric or catenary wire supplying a vehicle such as a train and an electric contact, for example a pantograph arm disposed on a moving vehicle and connected to a power distribution system thereof. The plasma is in contact with the electric or catenary wire and with an electric contact.

Abstract: A method and a system for increasing the lifespan of a plasma obtained in the atmosphere. The method includes the following steps: emitting a femtosecond laser pulse, referred to as a first pulse, generating a column of plasma by the filamentation phenomenon, and emitting a second YAG laser pulse, focused by way of an axicon on a line in the plasma column, the energy of the photons of the second laser pulse being greater than the attachment energy of the electrons in the plasma to neutral molecules such as oxygen molecules. The duration of the second pulse is greater than the duration of the first pulse, and the delay between the two pulses is greater than one microsecond.
