A frequency comb is generated with a Cr:forsterite femtosecond laser, spectrally broadened through a highly nonlinear optical fiber to span from 1.0 υm to 2.2 υm, and stabilized using the f-to-2f self-referencing technique. The repetition rate and the

We describe current measurement capabilities as well as research focused on two areas: improving temporal and frequency response characterization of detectors and instrumentation using electro-optic sampling, and improving wavelength metrology using

Fiber-laser-based frequency comb with a tunable repetition rate

Brian Washburn, R W. Fox, Nathan R. Newbury, Jeffrey W. Nicholson, K Feder, Paul S. Westbrook, C. G. Jorgensen
A phase-locked, self-references frequency comb generated by a mode-locked fiber soliton laser with a tunable repetition rate is presented. The spacing of the frequency comb is set by the laser?s repetition rate, which can be scanned from 49.3 MHz to 50.1

Infrared frequency comb for frequency metrology based on a tunable repetition rate fiber laser

September 1, 2004

Brian Washburn, Scott Diddams, Nathan R. Newbury, Jeffrey W. Nicholson, Feder Kenneth, Paul S. Westbrook, C. G. Jorgensen
A phase-locked, all-fiber supercontinuum source based on an ultrashort fiber ring laser with a tunable repetition frequency is presented. The supercontinuum output comprises a frequency comb with a spacing set by the laser repetition rate and an offset set

A phase locked, fiber laser-based frequency comb: limit on optical linewidth

Brian Washburn, Scott Diddams, Nathan R. Newbury, Jeffrey W. Nicholson, M. Yan, C. G. Jorgensen
A phase-locked fiber laser-based supercontinuum source is presented. The linewidth of a single line of the IR frequency comb produced by fiber laser-based supercontinuum source is less than or equal to}6 kHz.

Absolute frequency measurements with a stabilized near-infrared optical frequency comb from a Cr:forsterite laser

May 16, 2004

Kristan L. Corwin, I Thomann, Tasshi Dennis, R W. Fox, William C. Swann, E. A. Curtis, C. W. Oates, G Wilpers, A Bartels, Sarah L. Gilbert, Leo W. Hollberg, Scott Diddams, Nathan R. Newbury, Jeffrey W. Nicholson, M. Yan
A Cr:forsterite laser-based frequency comb is stabilized simultaneously to two NIST frequency references. Methane lines from 1315 nm - 1330 nm are measured with ±2.3 MHz uncertainty. The pressure shifts are also evaluated.

Absolute frequency measurements with a stabilized near-infrared optical frequency comb from a Cr:forsterite laser

Kristan L. Corwin, I Thomann, A Bartels, Tasshi Dennis, W. Fox, William C. Swann, E. A. Curtis, C. W. Oates, G Wilpers, Sarah L. Gilbert, Leo W. Hollberg, Nathan R. Newbury, Scott A. Diddams, Jeffrey W. Nicholson, M. Yan
A frequency comb is generated with a chromium-doped forsterite femtosecond laser, spectrally broadened in dispersion-shifted highly nonlinear fiber, and stabilized. The resultant evenly spaced comb of frequencies ranges from 1.1 to beyond 1.8 υm. The
