A device for generating and guiding an electric discharge current including a first electrode, second electrode and a material arranged between the first and second electrode. The device uses a laser for generating photons having energies equal to the energy between two excited electronic states of the material. The photons fill a region of the material from the first electrode through the material to the second electrode ionizing the region of the material between the first and second electrodes. A voltage generating unit connected to the first and second electrodes applies a voltage between the first and second electrodes thereby generating the electric discharge which follows an ionized path in the region between the first and second electrodes.
