Andreas Poppe studied communication engineering at the Vienna University of Technology. He wrote his diploma thesis on the "Stability measurements of short pulsed lasers" in 1996. For his PhD thesis he successfully implemented the first experimental direct access to the electric field of short laser pulses, especially the carrier-envelope-phase. He built up a high power laser oscillator with low repetition rate to extend the field of nonlinear optics to oscillators as well as a frequency comb setup together with the group of Prof Hänsch (Nobel laureate in 2005). At the spin-off company FEMTOLASERS he further developed the high power oscillator towards a commercial product. Back in basic research, Andreas joined the quantum cryptography project at the Institute of Experimental Physics (University of Vienna) headed by Prof. Zeilinger. Since then the major breakthrough was the first demonstration of a quantum cryptographic secured bank wire transfer. Together with his team he currently works towards long distance, high-secure quantum key distribution with entangled photons. Further research interests lie in the broad field of nonlinear optics and the corresponding applications like wavelength conversion and high-harmonic generation.
