Atomic clocks will be used in the future European positioning system Galileo. Among them, the optically pumped clocks provide a better alternative with comparable accuracy for a more compact system. For these systems, diode lasers emitting at 852nm a

We report a facile electrochemical route for the one-step fabrication of ZnO nanowire (NW) arrays. The method is seed-layer-free, and the NWs are directly attached to a fluorine-doped tin oxide (FTO) substrate. The effects of growth temperature, prec

We have step-irradiated Al-free laser diodes with 1 MeV electrons at fluences from 10 14 up to 10 16 electrons/cm 2 . We measure at each step their L-I and I-V characteristics to evaluate the impact of irradiation on optical and electrical properties

We have developed 852 nm laser structures, using an aluminium free active region. For an AR/HR coated ridge device, we have obtained an optical power of 320 mW in a single spatial mode with the beam quality parameter M/sup 2/=1.5.
