Temporal Methods Ultrafast Gating

The recovery of the full Raman spectrum of a deeply buried layer in a turbid sample was accomplished using the Kerr gating approach by Matousek and coworkers [13], on a two-layer powder sample, building upon pioneering research 

A more extensive description of the concepts and underlying mechanisms is provided in a tutorial review [18], 

The Kerr-gated Raman concept proved to be effective, although the complexity and high peak intensities involved in these experiments precluded its wider use. These Hmitations were lifted by the subsequent development of the spatial concepts for deep, noninvasive spectroscopy.
