Non-linear Spectroscopic Studies

Skip Navigation Links

  This research activity is concerned with the spectroscopy of
ultra-fast laser interactions non-linear optical measurements. One of
the common themes of this diverse activity is the understanding and
control of these interactions using adaptive temporal pulse
shaping. For example, the influence of ion beams measured using Time
of Flight (TOF) spectroscopy, and the spectral properties of laser ablation plasmas.
Also included are diagnostics for the non-linear optical
properties of novel materials such as 3-D photonic crystals. Our main
interests are in the measurements of nonlinear refractive index
(z-scan) and pump induced band gap shifts characterized using white light.
