title: A nonlinear approach to surface-enhanced sensing in the short-wave infrared.
abstract: The surface-enhanced hyper-Raman scattering (SEHRS) of three analyte molecules has been obtained with excitation wavelengths at 1.55 and 1.8 μm. At 1.55 μm, excellent signal-to-noise ratios under modest experimental parameters demonstrate compelling potential for practical applications in chemical analysis and molecular imaging.
