    Laser oscillation of Er3+:YVO4 and Er3+, Yb3+:YVO4 crystals in the spectral range around 1.6 μm (2000)

    Notes: Abstract. Laser oscillation around 1.6 μm was realised at room temperature for low-doped Er:YVO4 crystals (0.5 at % and 1 at %) as well as for Er(1 at %), Yb(5 at %):YVO4 crystal in continuous-wave mode. The maximum slope of the input–output curve was about 19% (vs. absorbed power) for Er(0.5 at %):YVO4. The laser oscillation was discretely tunable in the spectral range between 1531 and 1604 nm.

    Remote Anisotropic Effects in Diastereomeric Esters of Fluorinated O-Aryllactic Acids (2000)

    Notes: ---The enantiomeric purity of a chiral compound is determined by NMR spectroscopic analysis of the diastereomers formed with a chiral derivatizing agent. Fluorinated O-aryllactic acids (FAC) 1 are efficient chiral reporters, whose spectacular remote anisotropic effects allow an easy identification and measurement of diastereomers. The remote effects are attributed to the particular design of FAC esters relative to other CDAs.
