Report on the
solid-state lasers by A.I. Ferguson (Strathclyde Univ., Glasgow, U.K.).
EQEC'93
The successive plenary lectures dealt with some of the most topical aspects in quantum electronics, quantum optics, nonlinear optics and cavity quantum electrodynamics in multi quantum well devices, atom optics and atom interferometry, mesoscopic quantum coherence in cavity QED, electric dipole moments in atoms and neutrons, and applications of adaptive optics in astronomy.
European Quantum Electronics Conference 1993 The fourth European Quantum Electronics Conference (EQEC'93) was held September 10 to 13, 1993 at Firenze, Italy. This conference, promoted by the Quantum Electronics and Optics Division of the European Physical Society, is the major European forum for the growing number of European scientists to discuss and present their work concerning the various aspects of quantum electronics, laser physics or its applications. Starting in 1988 the EQEC is held biennial since 1989. This year the EQEC included the 7th Italian Conference on Quantum Electronics (EQUAP). The conference took place at the Villa del Poggio Imperiale in an impressive picturesque environment. It was organized by M. Inguscio and G. C, Righini (Conference Co-Chairs) and J. Mlynek (together with M. Inguscio Program Co-Chairs). This year 362 participants from 25 countries including an encouraging large number of students and young scientists made use of the rich program. It comprised 1 plenary session, 10 plenary lectures, 28 invited papers and 267 contributed papers including 186 posters. Forced by the satisfactory large number of contributions the oral presentations had to be organized in two or three parallel sessions covering the fields of laser device physics, laser spectroscopy, nonlinear processes, optical physics, quantum optics, ultrafast processes, and basic appfications. The conference was opened by an interesting review about the state of the art and future developments of
E.O. GObel (Univ. of Marburg, FRG) investigated the coherent coupling of free and bond excitonic transitions as well as transitions arising from spacially separated quantum-well structures by femtosecond spectroscopy. W. Erimer (Univ. of Bonn, FRG) discussed atom interferometry with trapped neutral atoms and showed first results for the measurement of the Scalar Aharonov Bohm effect with atoms. Additionally he presented first results for the diffraction of a metastable neon beam by a standing evanescent wave. S. Haroche (ENS, Paris, France) explained the transition from the quantum regime to the classical regime in the interaction of circular Rydberg atoms with fields of a few photons in a high Q cavity utilizing the measurement of their de Broglie wave phase shift in a Ramsey interferometer. Very impressive was the demonstration of a new "infrared camera" by F. Capasso (AT&T Bell Labs., Murray Hill, USA) based on a molecular-beam epitaxy lattice matched on a semi-insulating InP-substrate consisting of forty Si doped 10.5 nm thick InGaAs wells separated by 10 nm AllnAs barriers. Y. Yamamoto (Stanford Univ., USA) discussed spontaneous emission arising from cavity-QED effects in multi-quantum well devices. F. Merkle (ESO, Garching, FRG) explained the advantages of adaptive optics to improve drastically the resolution of modern optical telescopes.
One morning session was exclusively devoted to a tribute to Veniamin Chebotayev by W.R. Bennet Jr. (Yale Univ., USA), B. Cagnac (Univ. Paris VI, France), P. Franken (Univ. of Tucson, USA), and K.M. Evenson (NIST in Boulder, USA). The flavor of this EQEC was dominated by the enormous progress and the high level of the art which has been achieved in the recent past not only in young fields like atom optics or laser cooling but also in well established fields like e.g. generation of higher harmonics, optical parametric amplifiers or fiber lasers, to name a very few. This became also evident in many vivid discussions at the poster sessions, which were as well attended as the sometimes crowded topical sessions. Despite the fact that the attractions in Firenze were a strong competition to the conference the level of participation on the conference stayed remarkably good. May be that this was a consequence of the convincing cultural events, a vocal concert at the conference site and a concert in the church of San Giuseppe. Lust but not least the Italian charm reconciled for a few technical problems (mainly due to the ancient conference building). The 5th EQEC will be held this year in parallel with the CLEO/Europe'94 at the RAI Congress Center in Amsterdam, The Netherlands, August 28 September 2, 1994. This will be the first European Conference on Lasers and Electro-Optics in Europe. Detailed information can be obtained by the Quantum Electronics and Optics Division of the EPS. W. Ertmer
