Abstract
Surface-enhanced analogues of coherent Raman scattering (CRS) methods are promising candidates to probe molecular vibrations at much faster rates than what can be achieved with surface-enhanced Raman scattering (SERS). Thus far, experimental challenges have prevented surface-enhanced versions of CRS from growing into a practical tool. One of the major hurdles is the fragility of metallic antenna systems that support surface plasmons when illuminated with ultrafast pulses, causing photo-induced damage to the enhancement structures and lowering the repeatability of surface-enhanced nonlinear Raman measurements. In this contribution we discuss several implementations of surface-enhanced coherent anti-Stokes Raman scattering (SE-CARS) that avoid the use of metallic structures and use dielectric antenna systems instead.
