X-ray Lasers: Extreme brightness at short wavelength

These lectures will build up on fundamental concepts of how light interacts with materials to show how intense X-ray laser beams can be generated. The lectures will describe how efficient plasma heating techniques allow for the generation of bright soft x-ray lasers on a table-top. Applications of soft x-ray lasers in ultra-high resolution imaging, nano-scale materials characterization and modification, and other fields will be discussed.


Jorge Rocca is a Distinguished Professor at the Department of Electrical and Computer Engineering and Physics Department, Colorado State University, USA. He served as Director of the NSF Center for Extreme Ultraviolet Science and Technology. He received a diploma in Physics from the University of Rosario in Argentina in 1978 conducting research at CITEFA, and a Ph.D in ECE from Colorado State University in 1983. His research group demonstrated the first gain-saturated table-top soft X-ray laser using a discharge plasma as gain medium, and later extended bright high repetition rate table-top EUV lasers to wavelengths down to 8 nm using laser-created plasmas, achieving full phase coherence. He and his collaborators have demonstrated the use of these lasers in nano-scale imaging, dense plasma diagnostics, nano-scale material studies, and photochemistry. He has published more than 200 peer review journal article on these topics. Prof. Rocca received the Arthur. L. Schawlow Prize in Laser Science from the American Physical Society in 2011, and the Willis E. Lamb Award in Laser Science and Quantum Optics in 2012. He is a Fellow of the American Physical Society, the Optical Society of America, and the Institute of Electrical and Electronic Engineers. He was an IEEE LEOS Distinguished Lecturer for 2006-07, and early in his career he was an NSF Presidential Young Investigator.

Semiconductor LED Materials

This course comprises two talks of about 90 minutes each and is planned for advanced undergraduate or novice graduate students in Natural Science or Engineering. Basic concepts on Semiconductor Physics will be presented, with special emphasis on p-n homo and heterojunctions and luminescence induced by electrical current (electroluminescence) phenomena, with the purpose of providing a general view on properties and technology of active LED materials. Within this context, the history of LED devices will be critically and briefly discussed, starting from their origins as indicators to current LED applications in photonics and lightening.

Quantum information with multidimensional quantum systems

These three lectures are devoted to show how multidimensional quantum systems can be used in a more efficient manner for quantum information processing. In the first lecture, we will show the basic elements of quantum information with D-dimensional quantum systems (qudits). We shall also show how qudits can be used for general characterization of quantum channels. The physical implementations of qudits, in particular those based on single a two-photons states, will be also addressed. During the second lecture, we will show the use of qudits for implementing more secure quantum key distribution protocols and quantum states reconstruction. Finally, the last lecture will shown the use of qudits for fundamental tests of quantum theory and the state of the art of feasible applications for long distance quantum communication.

Carlos Saavedra is the Scientific Director of the Center for Optics and Photonics and Professor of Physics Department at Universidad de Concepción, Chile. He receded a PhD in Physics form Catholic University of Chile (1992). Between 1997 and 1998, he was an invited researcher at the Institute for Theoretical Physics, University of Innsbruck, Austria.
