Welcome to the research group of Prof. R. Jason Jones located within the James C. Wyant College of Optical Sciences at the University of Arizona. Our research spans a broad range of interests from precision spectroscopy with fs frequency combs, development of next generation optical atomic clocks, to ultrafast laser science.
