The 2016 Robert Hofstadter Memorial lecture will be given by Prof. Theodor W. Hänsch, Director of the Max-Planck Institute for Quantum Optics and Professor of Experimental Physics and laser spectroscopy at the Ludwig-Maximilian University in Munich, Germany. Prof. Hänsch is the co-recipient of the 2005 Nobel Prize in Physics for "contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique.” This method allows us to count the frequency of light, and is one of the most dramatic advances in optical metrology. Prof. Hänsch has made seminal contributions to laser spectroscopy and is the recipient of numerous scientific awards. The evening lecture will be held on Monday, April 25, 2016, followed by a Tuesday colloquium on April 26, 2016. More information will be posted here.
