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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
