Femtosecond light pulses tunable from 600-760 nm are generated by frequency doubling of an optical parametric oscillator in a Lithium Triborate crystal. The phase-matching bandwidth is shown to be the main limitation for harmonic generation of fs-pulses. By a dispersive element the phase-matching bandwidth and the conversion efficiency can be enhanced.
We analyze the predictions for CP asymmetries in B o -meson decays within the framework of the supersymmetric standard model (SSM). It is pointed out that owing to sizable new contributions to B od -B od andK o -K o mixings, the experimentally allowed range for the CP-violating phase δ of the Cabibbo-Kobayashi-Maskawa matrix may be different from...
