A 420 MHz Cr:forsterite Femtosecond Ring Laser and Its Use for Continuum Generation in the 1-2 Micron Range

August 1, 2003
Author(s)
I Thomann, A Bartels, Kristan L. Corwin, Nathan R. Newbury, Leo W. Hollberg, Scott Diddams, Jeffrey W. Nicholson, M. F. Yan
We demonstrate a chromium-doped forsterite femtosecond ring laser that generates 30-fs pulses at a 420-MHz repetition rate with nearly 500 mW of average power. The compact solid-state design and broad spectral output make this laser attractive for

Impact of Technical Noise on Supercontinuum Generation in Microstructure Fiber

June 1, 2003

Brian Washburn, Kristan L. Corwin, Nathan R. Newbury, R Windeler
The influence of the input laser technical noise on the noise of a generated supercontinuum is experimentally and numerically investigated. The supercontinuum technical noise is an amplified version of the input technical noise.

Fundamental Noise Limitations to Supercontinuum Generation in Microstructure Fiber

March 21, 2003

Kristan L. Corwin, Nathan R. Newbury, J M. Dudley, S. Coen, Scott Diddams, K Weber, R Windeler
Broadband noise on supercontinuum spectra generated in microstructure fiber is shown to lead to amplitude fluctuations as large as 50% for certain input laser pulse parameters. We study this noise using both experimental measurements and numerical

Raman Gain: Pump-wavelength Dependence in the Single-Mode Fiber

July 15, 2002
Author(s)
Nathan R. Newbury
The magnitude of the stimulated Raman gain spectrum will depend on the absolute pump wavelength. Measurements of the pump-wavelength scaling of the stimulated Raman gain of several single-mode fibers are presented. The measurements were obtained by use of

Broadband Noise on Supercontinuum Generated in Microstructure Fiber

January 1, 2002
Author(s)
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.

Pump-wavelength Dependence of Raman Gain

January 1, 2002
Author(s)
Nathan R. Newbury
The scaling of the Raman gain with pump wavelength is determined by three complimentary techniques: gain comparison at different pump wavelengths, gain asymmetry at a fixed pump wavelength, and theory combined with known fiber properties.
