Techniques like Two-Photon Excited Fluorescence (TPEF) and Coherent Anti-Stokes Raman Scattering (CARS) allow for deep, label-free, 3D imaging of biological tissues. oejournal

The field emerged in at the University of Michigan following the invention of the laser. It is governed by the nonlinear susceptibility tensor ( χ(2)chi raised to the open paren 2 close paren power χ(3)chi raised to the open paren 3 close paren power enabling high efficiency at lower powers.

High-quality nanophotonic devices enhance nonlinear effects by confining light into extremely small volumes, enabling high efficiency at lower powers.

Engineered "meta-mirrors" and thin films can exhibit nonlinear responses millions of times larger than conventional crystals. Key Applications NLO systems are critical across several high-tech domains:
