Tolk's group

Vanderbilt University’s Center for Molecular and Atomic Studies at Surfaces (CMASS) has  attractive and vigorous research programs in linear and nonlinear optics as well as in  time-resolved (pump-probe) ultrafast spectroscopies. Experimental facilities include an array of ultrafast lasers located in three labs.  Specifically, we have research projects in the fields of

  • Coherent Acoustic Phonon Spectroscopy
  • Ultrafast Pump-Probe Reflection/Transmission Spectroscopy
  • Second Harmonic Generation

We apply these techniques to various types of semiconductors with nanostructures such as multilayers, nanocrystals and two dimensional materials.
