Description
Few-femtosecond laser pulses offer a unique potential to control various electron processes in solid-state media. These include the generation of hot electrons [1], inducing nonadiabatic tunneling photoemission [2] and inducing the transient metallization of dielectric media [3]. In my talk, I will review recent experimental progress of the Wigner Research Centre for Physics in each of these fundamental research fields. In addition, I will also present first real-life applications of these phenomena such as the construction of an optical chip detecting the phase shift in femtosecond laser beams.
