Ultrafast currents created upon interaction of few-cycle lasers with solids

Seminar

Seminar talk

Vaclav Hanus (Wigner Research Centre for Physics, Budapest, Hungary)

When the intensity of the laser reaches a level where its electric field approaches that of atoms, various nonlinear phenomena can occur during its interaction with solid matter. One particular phenomenon that has garnered attention is the generation of ultrafast currents. These currents are so fast that they can follow the shape of the electric field of the laser.

To manipulate the electric field easily, the experiments utilize carrier-envelope phase (CEP) modulation, enabling the alteration of the direction of these ultrafast currents in dielectrics and semiconductors. In this talk, I will showcase experiments along with a recent application of ultrafast currents to construction of a CEP scanning probe. Additionally, I will discuss the properties of a potential device based on these ultrafast currents.
