Alessandra Toncelli

Universita' di Pisa, Italy

Alessandra Toncelli received her Ph.D. degree in physics from the University of Pisa in 1998. She continued to work in research with various postdoc and researcher positions both in Italy and abroad. In 2005, she became a Researcher at the University of Pisa. Her research interest is mainly devoted to the growth and spectroscopy of active media for photonic applications in the visible and near-infrared wavelength regions. She studied the optical and spectroscopic features of oxide and fluoride crystals doped with rare earth ions (RE). Up to now, she optimized the growth and characterization of various materials doped with various types of RE. Laser emission has been obtained from many of these samples in various regions from UV (Ce) to the visible (Pr) to near infrared (Nd, Tm, and Ho) with efficiencies among the best ever published in international journals. In 2002, she set up a micro-pulling-down furnace for the growth of oxide and fluoride monocrystal fibers. Many oxide and fluoride fibers have been grown with diameter smaller than 1 mm and length up to 30 cm; among the various compounds, lithium niobate fibers up to 30 cm long have been grown. Moreover, in the frame of a collaboration with the VIRGO project, she recently grew silicon monocrystal fibers to be investigated as possible last-stage mechanical suspensions for the mirrors in interferometers for gravitational wave detection. She recently devoted her research interest in the study of fluoride nanoparticles for photonic and biomedical applications. In all these research areas, she has published more than 90 articles in international journals and more than 50 contributions to national and international congresses up to now. She currently has various national and international collaborations for crystal growth, spectroscopic investigation, and laser applications. She has been a national and local coordinator of various national projects. She has also been in the organizing committee of various international conferences.
