Abstract: This paper supports the improvement of research, the theoretical and practical aspects of the CO2 laser. Since the first CO2 laser, various research has been carried out which has improved the technology of ferrous and non – ferrous material processing due to the tunable wavelength of 8,7-11,8µm which allows the use of this cutter in various technological cutting operations, drilling, welding. The CO2 laser lines are very intense in the infrared range, and this is obtained by splitting the levels in the subwoofers due to columbic energy and hyperfine splitting due to vibration and rotation, so that the spectrum of the polyatomic molecule is more complex and complicated, making it successfully used in industrial and naval engineering.
Brief Biography of the Speaker: Badea Lepadatescu is currently an Associate Professor at the Faculty of Technological Engineering and Industrial Management of Transylvania University of Brasov, Romania. He obtained his doctoral degree in 1998 in the area of machining through superfinishing process. After he graduated he worked five years as design engineer at Roman truck factory in the field of manufacturing processes where he designed many devices and special machine tools especially for superfinishing process. Started on 1982 he worked as research engineer at Transilvania University of Brasov, and after 1997 he is teaching at Department of Manufacturing Engineering. His main academic interests include Tolerance and Dimensional Control, Manufacturing Engineering Processes, Automation Processes, and Renewable Energy Sources. The research accomplishments are reflected through publications in a eight books and authored or co-authored over 130 papers published at international conferences. He has extensive experience in both experimental and theoretical research work having more than 50 contracts with factories to design and produce machine tools for machining processes. Also in the field of Renewable Energy Sources together with a team he made wind turbines, with horizontal axis for taking water, and with vertical axis to produce electric energy. He has been speaker to international conferences, has moderated forums, organized symposia, workshops and sessions at major international conferences.
