Leo Hollberg
Lecturer. Ph.D. University of Colorado, 1984.
Research interests include high precision tests of fundamental physics
as well as applications of laser physics and technology. The research involves
the study of laser noise and various approaches up to, and beyond, quantum
limited optical detection. The present effort focuses on developing and
using semiconductor diode lasers technology for atomic physics and precision
measurements. Two areas of application are laser detection of isotopes
and optical frequency synthesis.
