Abstract

We study improving of spatial resolution of fluorescence microscopy by using dark states formed via interaction with bi-chromatic optical fields. This approach has applications to coherent Raman spectroscopy.

Nanoscale resolution fluorescence microscopy using electromagnetically induced transparency

Deniz D. Yavuz, Nicholas Proite

We suggest a type of scanning fluorescence microscope that is capable of resolving nanometer-size objects in the far field. The key idea is to use the spatial sensitivity of the dark state of electromagnetically induced transparency and localize an atomic excitation to a spot much smaller than the wavelength of light.

Optical microscopy at the sub-nano scale via coherent population oscillations

Kishore T. Kapale, Wa Kun Lam, G. S. Agarwal

We present methods for microscopy beyond the Rayleigh limit through the phenomena of coherent population oscillations. The atomic fluorescence shows sharp spatial features offering resolution below one nanometer using spatially shaped pump and probe beams.
