John Hall
Nobel Laureate John Hall was instrumental in developing the Optical Frequency Comb.

Nobel Laureate John Hall is the featured speaker at the Center for High Technology Materials (CHTM) Distinguished Lecture Friday, May 6 at 10 a.m. The lecture titled, “Intracavity Nonlinear Spectroscopy, technical issues, and scientific opportunities,” will be held in CHTM room 103. A discussion follows the lecture.

Hall, a lecturer in the physics department at the University of Colorado-Boulder, shared the 2005 Nobel Prize in Physics with T.W. Hänsch and Roy Glauber for "contributions to the development of laser-based precision spectroscopy, including the optical frequency comb technique."

He will discuss cavity-enhanced spectroscopy by its coherent field build-up transforms a few ppm absorption into some percent of changed transmission, and organizes interaction with free-flying molecules such that most interactions with the probing light lead to a detected change in the observed light. So with vibration-insensitive cavity design, one is looking at a lunch-box-sized replacement for the best currently-commercial quantum oscillator, the Hydrogen maser.

He has authored more than 230 articles in refereed journals and holds ten U.S. patents. He is a member of the National Academy of Sciences and is a Fellow of the Optical Society of America and the American Physical Society. He is also a Senior Fellow Emeritus of the National Institute of Standards and Technology and a Fellow Adjoint of JILA.

Hall has trained numerous graduate students and post docs in the Physics Department at the University of Colorado, Boulder. His JILA work has been recognized through a number of awards from NIST, the Department of Commerce, and the U.S. Office of Personnel Management. He has been awarded many professional, peer-generated honors by the Optical Society and the American Physical Society. In 2004, he received the IEEE Rabi Award and became a member of the French Légion d'Honneu.
