Broadband Noise on Supercontinuum Generated in Microstructure Fiber

January 1, 2002

Kristan L. Corwin, Nathan R. Newbury, Sarah L. Gilbert, K Weber, Scott Diddams, Leo W. Hollberg, R Windeler
The broad supercontinuum generated by pumping highly nonlinear microstructure fiber with a femtosecond laser exhibits broadband amplitude noise. We experimentally investigate this amplitude noise as a function of wavelength, input pump power and chirp.

A suitable femtosecond (fs) laser system can provide a broad band comb of stable optical frequencies and thus can serve as an rf/opticalcoherent link. In this way we have performed a direct comparison of the 1 S - 2S transition in atomic hydrogen at 121 nm

All-Optical Atomic Clocks

Scott A. Diddams, T Udem, K R. Vogel, Christopher W. Oates, E A. Curtis, W D. Lee, Wayne M. Itano, Robert E. Drullinger, James C. Bergquist, Leo W. Hollberg
Microwave atomic clocks have been the de facto standards for precision time and frequency metrology over the past 50 years, finding widespread use in basic scientific studies, communications, and navigation. However, with its higher operating frequency, an

Lasers, Ultrafast Pulse Technology

Tracy S. Clement, Scott Diddams, David J. Jones
Ultrafast pulse technology refers to the generation and use of laser pulses with durations in the femtosecond range. These ultrafast pulses are useful for a variety of applications ranging from the scientific study of very fast chemical and biological
