Theodor Hansch

Theodor Wolfgang Hänsch is a German physicist. He is the recipient of the Nobel Prize in Physics 2005, which he shared with John L. Hall and Roy J. Glauber. He received the prize for his discoveries concerning advancing optics technology, including the development of optical frequency comb technique in the field of laser-based precision spectroscopy. His research in optics technology enabled the color of the light of atoms and molecules to be determined with exceptionally high precision.

Hänsch  was a professor at Stanford University from 1975 to 1986, and he is currently working at the Max Planck Institute for Quantum Optics as the Head of research and at the Ludwig-Maximilians University in Munich as Professor of experimental physics and laser spectroscopy. His growing collection of prizes includes the 1986 Albert A. Michelson Medal, the 1989 Gottfried Wilhelm Leibniz Prize (the highest honour awarded for scientific research in Germany), the 2005 Otto Hahn Award and the Frederic Ives Medal. In 2008 he became the honorary member of the Optical Society of America.
