Abstract
Research program Optodynamics and laser applications consists of two closely related parts. The first part (optodynamics) deals with basic research of dynamic aspects of interaction between light and matter and is primarily oriented toward education of young researchers. The second part (laser applications) deals with applicative research and development in the field of laser manufacturing and measurement systems. It is a systematic research and development support to introducing laser technology into Slovenian industry. The term optodynamics is an original name for a new, interdisciplinary field which includes a wide range of phenomena, from photoacoustic effect, laser-induced shock waves, optical ultrasonics, laser manufacturing processes, applications in medicine to laser-induced nuclear fusion. Optodynamics research is concentrated on the theoretical basis of laser-induced dynamic phenomena, research of the physical foundation of laser manufacturing processes and research of optodynamic processes in liquids. Included in the field is research of new measurement methods for studies of optodynamics, among which the emphasis is on fiber optic sensors. Currently the work is concentrated on the humidity sensor with an original detection geometry and on the temperature sensor based on fluorescence time of a doped crystal. The emphasis of the applicative part of the program is closely connected with the development of industrial lasers and systems of the Slovenian manufacturer (Fotona) and applying laser technology to various branches of industry. The main part is the research of laser manufacturing processes (marking, cutting, welding, bending) and laser supported measurement methods. Open questions remain the characteristics of laser mark (depth, visibility, permanency), the optimization of parameters of laser marking and the use of new laser sources (Er:YAG, Ho:YAG). A worldwide novelty is the research of laser cutting at an angle, offering possibilities of manufacturing prototypes of complex shapes. In the field of laser welding new methods are being examined for monitoring the process with the aid of optoacoustic signals analysis. Application research is also going on with the development of a laser measurement of profile, based on optical triangulation. It is special in the use of anamorph optics both for shaping the structured light and for projection of the reflected beam into the digital camera. The system offer many possibilities for measuring the shape of objects.
