Observation of new laser transitions and saturation effects in optically pumped NO

Applied Physics B Photophysics and Laser Chemistry 54:2 (1992) 119-125

Abstract:

We report investigations of an NO laser employing specially profiled magnetic fields of up to 3.4T, and F2 pump laser intensities as great as 20 MW cm-2. We have observed laser oscillation at 226 nm on a rotational branch of the B'-X/it(3-11) band of NO for the first time, in addition to the previously reported oscillation at 218 nm on the B'-X/it(3-10) band. We have also observed visible laser emission on a rotational branch of the B′2Δ-B2II(3-1) band of NO. Saturation of the NO laser pulse energy with pump intensity has been observed, the total NO laser pulse energy having been increased to 490 μJ. The possibility of increasing the NO laser pulse energy towards 1 mJ per transition is discussed. © 1992 Springer-Verlag.

Abstract:

The forward-backward asymmetry in the reaction e+e-→bb has been determined at centre of mass energies near 35 GeV using the TASSO detector. We report results from three different methods. The combined result of the measurements is {Mathematical expression} ignoring {Mathematical expression} mixing. Taking mixing into account leads to a corrected asymmetry of {Mathematical expression}. The axial vector coupling constant of the b quark as calculated from the corrected asymmetry is ab=-1.2±0.5 to be compared with the value abSM=-1 from the standard model. © 1990 Springer-Verlag.

Observation of laser oscillation in nitric oxide at 218 nm.

Opt Lett 15:8 (1990) 437-439

Authors:

SM Hooker, CE Webb

Abstract:

We have recently proposed a scheme to produce coherent radiation at eight or more wavelengths between 158 and 242 nm by optically pumping a high-lying electronic level of nitric oxide. We report here the successful operation of this scheme to produce laser oscillation at 218 nm. The possibility of using this scheme to produce laser oscillation at other wavelengths is discussed.
