research overview

  • The research of Dr. Becker and his group is focused on the theoretical analysis and numerical simulations of ultrafast processes in atoms, molecules and nanostructures, which can be observed and controlled using intense laser pulses. Applications can be found in basic and applied research. The study of the response of matter to electromagnetic radiation is closely related to the development of intense laser systems generating ultrashort light pulses. The strengths of these light fields exceed that of the Coulomb field within an atom or molecule while the pulse lengths have decreased below the femtosecond (10^-15 s) barrier and a new research area called attoscience evolved.
