Abstract

We demonstrate both theoretically and experimentally that a proper surface modification of a highly scattering material can substantially improve light coupling into turbid medium and increase the photon life-time in this medium. As a practical example, we demonstrate that such amended excitation geometry leads to a factor of 100 improved Raman signal efficiency.
