Franson, Nonlinear Optics at Ultra-Low Power Levels using Metastable Xenon in a High-Finesse Optical Cavity, https://arxiv.org/abs/1404.0376v1http://hdl.handle.net/11603/19350Strong saturated absorption at nanowatt power levels has been demonstrated using metastable xenon in a high finesse optical cavity. This approach provides a relatively simple method for generating nonlinear optical effects, such as single-photon cross-phase modulation, without the need to trap atoms within a cavity. The use of metastable xenon allows a high quality factor of Q=2*10^8 to be achieved at relatively high atomic densities without any contamination or damage to the optical surfaces, which is often a problem when using high-density rubidium or other alkali atoms.6 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
