Lay summary
The partners:Prof. Antoine Weis, University of Fribourg, Switzerland Prof. Brana Jelenkovic, University of Belgrade, Serbia Dr. Todorka Dimitrova, University of Plovdiv, BulgariaBackground:High level university teaching of physics has to build on a solid knowledge of classical physics. In most European universities the teaching of introductory classical physics is accompanied by lecture demonstration experiments, whose aim is to show basic physical phenomena to the students and to illustrate the experimental techniques underlying physical measurements. Lectures are complemented by student laboratories in which students get acquainted with the basic experimental techniques and the application of those techniques to specific quantitative experiments. However, for teaching modern (20th century) physics - in particular modern optics and elementary quantum mechanics - demonstration experiments are scarce, and lectures become progressively purely theoretical teaching units. The internet offers a wealth of information, sometimes illustrated by practical simulations that illustrate theoretical concepts in advanced lectures. Nevertheless, we strongly believe that the best of simulations will never be a substitute for the didactical advantages of illustrative hands-on demonstrations or student laboratory experiments. (150)Goal:The goal of the project is the development of lecture demonstration and advanced student laboratory experiments in Modern Optics (MO), Laser Physics (LP) and Optical Laser Spectroscopy (OLS) and Magneto-optical laser spectroscopy (MOLS). A total of 20 individual modules will be developed with an emphasis on modular design that allows the use of several components in different experiments. The topics covered include: fiber optics, Nd:YAG and He-Ne lasers, holography, laser gyroscope, wave-particle duality of light, optical tweezers, linear and nonlinear Faraday and Hanle effect, light shift visualization, two-photon and saturation spectroscopy.Significance:The role of demonstration and laboratory experiments in university level education cannot be overestimated. The fast development of novel technologies requires an adapted education and the involvement of new specialized disciplines. Obviously, university teaching in Eastern Europe is not able to offer its students corresponding demonstration and laboratory equipment and most of the modern courses are mainly theoretical. This is also partly true for small cantonal Swiss universities, in which lack of human resources often prevents a modernization of equipment in those fields.

Abstract

In this project the teams of Prof. Antoine Weis at Université de Fribourg (Partner 1, coordinator), Prof. Brana Jelenkovic at University of Belgrade, Serbia (Partner 2), and Dr. Todorka Dimitrova at University of Plovdiv, Bulgaria (Partner 3) will join forces to bring experiments and research results from modern optics, laser physics, and laser spectroscopy to the teaching environment, both as lecture demonstration and in student laboratory experiments.Any high level teaching of physics at the university level has to build on a solid knowledge of classical physics. In most European universities the teaching of introductory classical physics is accompanied by lecture demonstration experiments, whose main aim is to show basic physical phenomena to the students and to illustrate the experimental techniques that allow the observation (and quantitative measurement) of physical processes. In general, lectures are complemented by student laboratories in which students get acquainted first with the basic experimental techniques, and later with the application of those techniques to specific quantitative experiments. However, for teaching modern (20th century) physics - in particular modern optics and elementary quantum mechanics - demonstration experiments become scarce, and lectures become progressively purely theoretical teaching units. This is even more marked in advanced classes, in which students are introduced into the state of the art in research. The internet offers a wealth of information, sometimes illustrated by practical simulations, and many of us make use of it for illustrating theoretical concepts in advanced lectures. Nevertheless, the partners of the present project strongly believe that the best of simulations will never be a substitute for the didactical advantages of illustrative hands-on demonstrations or student laboratory experiments. It is therefore our declared goal to develop specific lecture demonstration and student laboratory experiments in which laser radiation plays a fundamental role. The topics to be attacked are subdivided into two categories: Modern optics and laser physics and High resolution laser spectroscopy, and a total of 21 subtasks will be attacked, mostly in bilateral collaborations.All three partners teach regular courses on modern optics and applications thereof. Partner 1 (coordinator) and 2 share a common research interests in the fields of laser and magnetooptical spectroscopy and have a strong wish to bring demonstrations thereof to their classrooms and student labs. Partner 3 is mainly involved in teaching at a university, in which research plays a subordinated role due to the very limited local funds. Partners 1 and 3 have collaborated in the past in developing demonstration experiments at the borderline of classical and quantum optics. The teaching equipment and student laboratories at the universities of both Eastern European partners (and to a lesser extend of the Swiss partner) are in strong need of renovation and modernization. The present project offers the opportunity to contribute to this goal. A particular attention will be given to realize the different experiments in a modular way, using fiber optics, so that various components can be used for several applications. Since demonstrations are only shown on a few occasions during the year, the modular design will allow the use of certain components for student research projects during most of the year. To our knowledge there are no national/international funding programs that support activities of the type envisioned here and the Scopes seems to us a unique opportunity to launch such an effort.Most of the activities will be carried out by young researchers and students under the guidance of experienced researchers.
