Coherent Interaction of Light and Single Molecules in a Dielectric Nanoguide [PDF]
, 2014 We present a new scheme for performing optical spectroscopy on single molecules. A glass capillary with a diameter of 600 nm filled with an organic crystal tightly guides the excitation light and provides a maximum spontaneous emission coupling factor ($\

Doppler-free Yb Spectroscopy with Fluorescence Spot Technique [PDF]
, 2010 We demonstrate a simple technique to measure the resonant frequency of the 398.9 nm 1S0 - 1P1 transition for the different Yb isotopes. The technique, that works by observing and aligning fluorescence spots, has enabled us to measure transition ...

Measurement and simulation of laser-induced fluorescence from non-equilibrium ultracold neutral plasmas [PDF]
, 2001 We report new measurements and simulations of laser-induced fluorescence in ultracold neutral plasmas. We focus on the earliest times, when the plasma equilibrium is evolving and before the plasma expands.
