Lez #51+52 RIKES Imaging

 We described the basics of RIKES: a vibrationally resonant combination of pump and stokes can induce optical anisotropy which generates an electric field along a direction orthogonal to the incoming stokes, via a four wave mixing process. This effect can be homodyne detected, or via balanced detection, to measure separately the real and imaginary parts of the non linear susceptibility.

Lez #49+50 CARS and SRS imaging, background suppression stategies

We have seen how to implement CARS and SRS imaging and what are pro and cons of the two approaches. We discussed different strategies to suppress non resonant background accompanying CARS.

Lez #47+48 Imaging lineare e non lineare

We have seen the working principle of an imaging system based on linear and non-linear effects, with and without vibrational sensitivity
