Applied Lasers and Optics - Recent findings from A. Sherman and co-authors highlight research in applied lasers and optics

  2010 MAR 23 - (VerticalNews.com) -- "A method for measuring complex fast nonlinear optical nonlinearities chi ((3)) in waveguides is demonstrated. It is based on a comparison between the optical nonlinearities of two different samples under identical experimental circumstances and thus is independent of laser pulse parameters," scientists in Braunschweig, Germany report.

  "Heterodyne detected four-wave mixing is employed to achieve information about both amplitude and phase of chi ((3)). To increase the sensitivity, a procedure for suppression of the limiting parasitic signals due to the photodiode nonlinearity is suggested," wrote A. Sherman and colleagues ...read more


Applied Lasers and Optics - New applied lasers and optics research from Kyoto University described

  2010 MAR 23 - (VerticalNews.com) -- According to recent research from Kyoto, Japan, "We have successfully implemented the first simultaneous magneto-optical trapping (MOT) of lithium (Li-6) and ytterbium (Yb-174) atoms towards production of ultracold polar molecules of LiYb."

  "For this purpose, we developed the dual atomic oven which contains both atomic species as an atom source and successfully observed the spectra of the Li and Yb atoms in the atomic beams from the dual atomic oven. We constructed the vacuum chamber including the glass cell with the windows made of zinc selenium (ZnSe) for the CO2 lasers, which are the useful light sources of optical trapping for evaporative and sympathetic cooling," wrote M. Okano and colleagues, Kyoto University ...read more


Applied Lasers and Optics - University of California reports research in applied lasers and optics

  2010 MAR 23 - (VerticalNews.com) -- According to recent research published in the journal Applied Physics B - Lasers and Optics, "Four-wave mixing (FWM) is a well-known nonlinear optical phenomenon and has attracted great interest in nonlinear all-optical signal processing owing to its ultrafast and transparent properties. Here we report the experimental observation via spectra on the nontransparency and optical phase erasure characteristic of FWM. ...read more
