Cutting-Edge Research Facilities: Advanced Ultrafast Laser and Nanomaterials Processing Infrastructure



The Ultrafast laser micro- and nano- processing laboratory disposes state-of-the-art equipment in combination with highly specialized human expertise, capable of supporting cutting edge research projects of European researchers active in interdisciplinary scientific fields.
In particular the lab infrastructure comprise various short (nanosecond, picosecond) and ultrashort (femtosecond) UV, VIS and NIR laser sources combined with a series laser processing and nanomaterials synthesis and deposition workstations with in-line optical diagnostics. The lab also hosts various laser spectroscopy workstations including capabilities of Reflectivity (250-2500 nm/4K-380K), Photoluminescence spectroscopy (250-2500 nm/4K-380K), Valley Polarization (4K-380K) and Time Resolved Absorption (250-2500 nm) spectroscopy. Additive manufacturing facilities that combine 3D printing with laser subtractive manufacturing and sintering of inks, are additionally provided. Finally a fully customized multimodal non Linear Microscopy, Imaging and spectroscopy workstation is developed for materials diagnostics and in-situ monitoring of biological processes.
