We present a method to determine particle size distributions in powders, based on the polarization dependent second harmonic generation (SHG). Unlike existing methods, dilution is not required and is largely insensitive to the optical alignment.
The possibility of obtaining sub-diffraction limited spatial resolution with label-free imaging, based on coherent anti-Stokes Raman (CARS) microscopy, is investigated numerically. Like STED, CARS emission is strongly suppressed by applying an additional light field.
