Second harmonic generation (SHG) microscopy is a label-free, nonlinear optical imaging technique that exploits the frequency-doubling of incident photons in non-centrosymmetric structures. It provides ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

A new Houston Methodist study highlights a promising noninvasive imaging technique that could help doctors more accurately ...
