Interferometric differentiation between resonant Coherent Anti-Stokes Raman Scattering and nonresonant four-wave-mixing processes

, 2004
A major impediment of using Coherent Anti-Stokes Raman Scattering to identify biological molecules is that the illumination levels required to produce a measurable signal often also produce significant nonresonant background from the medium, especially ...

Hydrogen Halide Gas Sensors: Active Materials, Operation Principles, and Emerging Technologies

Interdisciplinary Materials, EarlyView.
This review considers hydrogen halide (HX) gas sensors across functional materials and principles: acoustic, chemical, optical and nanophotonic. The strong acidity and reactivity of HX gases are discussed as constraints for stability and selectivity of these devices.

Optical Nano-Imaging of Materials: Peeping Through Tip-Enhanced Raman Scattering

CHIMIA, 2006
High-resolution optical nano-imaging, with a spatial resolution far beyond the diffraction limits of the probing light, has been shown by means of tip-enhanced near-field Raman spectroscopy.

Nonlinear optical microscopies (NOMs) and plasmon-enhanced NOMs for biology and 2D materials

Nanophotonics, 2020
In this review, we focus on the summary of nonlinear optical microscopies (NOMs), which are stimulated Raman scattering (SRS), coherent anti-Stokes Raman scattering (CARS), second harmonic generation (SHG), and two-photon excited fluorescence (TPEF). The

Exploring, tailoring, and traversing the solution landscape of a phase-shaped CARS process [PDF]

, 2010
Pulse shaping techniques are used to improve the selectivity of broadband CARS experiments, and to reject the overwhelming background. Knowledge about the fitness landscape and the capability of tailoring it is crucial for both fundamental insight and ...
