I use a bunch of random stuff to make sure my microscope is working okay. One of those things is chicken fat… weirdly enough. Coherent Raman imaging is really useful for looking at lipids due to it’s naturally high ‘nonlinear susceptibility’ (jargon for how easy you can move electrons around, and thus change it’s local charge dynamics). In this picture, I’m using CARS (coherent anti-Stoke Raman scattering, green) and SRS (stimulated Raman scattering, red) to look at a lipid-dominant Raman signal (2850cm^-1). In most cases, you expect CARS and SRS signal to line up pretty well. In this case, that did not happen… and I am not exactly sure why. But nonetheless it resulted in a cool looking image.
