In vibrational microscopy, it is often necessary to distinguish between chemically distinct microscopic objects and to highlight the ‘‘chemical interfaces’’ present in the sample under investigation. Here we apply the concept of focus engineering to enhance the sensitivity of coherent anti-Stokes Raman scattering (CARS) microscopy to these interfaces. Based on detailed numerical simulations, we show that using a focused Stokes field with a sharp phase jump along the longitudinal direction leads… CONTINUE READING
