University of Ljubljana (SLOVENIA)
University of Ljubljana is the largest and the oldest institution of higher education in Slovenia. Chair for Optodynamics and Laser Applications (COLA) from Faculty of Mechanical Engineering was established in 1995 on the basis of ongoing R&D work in this field since the late 1970ies. COLA carries out teaching, research and development and knowledge dissemination in the fields of optodynamics (laser-induced material motion), optoacoustics and laser ultrasonics, laser-materials interaction, pulsed laser manufacturing processes (marking and engraving, drilling, ablation, cleaning, welding, forming,...), laser based measurement systems and opto-mechatronic systems. In 2006 COLA started research activities in the field of fiber lasers. In 2007 a new laboratory for R&D in the field of fiber laser technology was equipped with support from the industry.
Role in the project
Main contribution of the UNILJ will be the development of the new approach of the fiber laser q-switching based on single crystal photo-elastic modulator (WP1). A new driver will be developed that enable simultaneously excitation of several eigen modes of the crystal. Further the modulator will be tested in a fiber laser cavity and in cooperation’s with the other partners a Q-switched laser will be build. In addition within WP2 and WP3 a new PCF and new DFB seed laser diodes will tested and characterized.
The key personnel to be involved in the project activity:
: he received the diploma degree in Physics at the University of Ljubljana; Faculty of Mathematics and Physics in 1994. From 1994 to 2003 he was employed at Jozef Stefan Institute, the largest Slovenian research institutions. His main research field at that time was applications of liquid crystal displays and shutters, as well as interferometric length measurements. After he received his doctoral degree in 2003 he moved to the University of Ljubljana, Faculty of Mechanical Engineering and joined the Chair of Optodynamics and Laser Applications. His main research topic was monitoring of pulsed laser processing by detecting shock waves. In 2006 and 2007 he worked eight months at the Vienna University of Technology. At that time he started research in order to develop new approaches of fiber laser Q-switching. Till now he was involved in four international projects Inco-Copernicus Program “Volume stabilized chiral liquid crystals for display applications”, NATO SfP “Lcd optical light shutter for eye protection devices”, EU FP5: “Plasma assisted cost effective coatings for optics”, Leonardo da Vinci Program: “Laser technology educational network”. He participated to numerous scientific conferences and published 22 scientific papers.
