The International Symposium - Internet Presentation "Laser Technologies and Lasers ("LTL Plovdiv 2001") was held Sept.23-26, 2001 in Plovdiv and in Smolyan, Bulgaria. The Symposium was organized by Institute on Laser and Information Technologies - RAN, Russia, Institut National de Metrologie, Conservatoire National des Arts et Metiers, Paris, France and "Optela - Optical Technologies" - Joint-stock Company, Bulgaria. The main sponsor of the Symposium was "Optela - Optical Technologies". The co-organizers were Technical University-Sofia, branch Plovdiv, Bulgarian Academy of Sciences, University of Plovdiv, Union of Scientists in Bulgaria - Plovdiv, European Inter-University Centre of Medical Radiation Physics and Techniques - Plovdiv and Saedinenie Corporation - Plovdiv. The organizers intent was to provide a meeting place for bulgarian and foreign scientists and applied engineers working in the field of laser technologies and laser technique and physics. This meeting has to give them an opportunity to be acquainted with the latest achievements in hot topics in laser technology and laser technique and physics. In this meeting 8 invited scientific reports were delivered. The possibilities for discussions were further enhanced by the poster session. The "Optela - Optical Technologies" Company organized a special presentation-exhibition of its production. The Internet presentation of the reports abstracts was also given. About 60 scientists and engineers from Bulgaria, Russia, France, Greece, Japan and India attended the Symposium. The place of the Symposium was one of the beautifuls bulgarian towns - Smolyan. It is disposed in the Rhodopes Mountains. The evenings of the Symposium were provided in informal and relaxed atmosphere, typical for well-known Bulgarian hospitality. This permits very useful non-formal professional contacts between the participants. The organized excursion for the participants permits them to enjoy to the beauty of the tourist landmarks of the Rhodopes Mountains (Pamporovo, Rogen, visit of the Bulgarian National Observatory) and Plovdiv town.

The organizing Committee appreciates the support of Mr. Peter Nejchev, Director in "Saedinenie" Corp., Dipl.Eng.Peter Stajkov, Executive Director of "Optela - Optical Technologies" - JSCo, Prof. DSc. V. Ya. Panchenko and Prof. DSc. V. S. Golubev, IPLIT RAN, Prof. DSc. M. Himbert, Director INM, CNAM (France), DSc. J. P. Wallerand INM, CNAM, (France) and help of Dr. Eng. M. Deneva, TU-Sofia, branch Plovdiv and PhD student Eng. A. Boyadjieva, TU-Sofia, branch Plovdiv - scientific secretaries of the Symposium.
