Ultrafast nanooptics and plasmonics

Our research in this field is performed with the nearfield sensitive, space- and energy-resolved photoemission electron microscopy technique (PEEM). The available laser wavelengths include the whole visible spectrum up to the near infrared, and also 270 and 210 nm in the UV. Time-resolved measurements can be performed with subcycle resolution and time-steps as small as 50 as.

Research areas:

  •          Near-field control
  •          Magneto-optical effects
  •          Propagating surface plasmon (SPP) dynamics
  •          Plasmon induced hot carrier dynamics
  •          Fundamental light-matter interactions
