Single-cycle optical frequency combs
Scott Diddams
NIST and University of Colorado, United States of America
Built from robust Er:fiber lasers, we describe optical frequency combs generated with pulses approaching a single-cycle of light. When combined with chi-2 and chi-3 nonlinear optics such short pulses efficiently generate multi-octave frequency combs spanning from 350 nm to beyond 25 microns. We further demonstrate straightforward techniques for scaling the energy of the few-cycle pulses, which can then drive non-perturbative nonlinear optics in solids for harmonic generation below 200 nm. Applications of frequency comb spectroscopy across the full coherent spectrum, from the UV to the MIR, are being pursued.

Dual-comb ranging offers high precision and high accuracy distance measurements. However, the application of dual-comb ranging systems is restricted by the complexity of the setup and inherent length ambiguity. Here we present a new and simple approach to increase the ambiguity-free measurement range of dual-comb raining while simultaneously decreasing the complexity by using a single cavity dual-color-fiber laser. By exploiting the intrinsic intensity modulation of our laser we are able to measure distances up to 150 km without ambiguity in a single measurement.

We present a thin-disk laser oscillator generating two asynchronous pulse trains of 240-fs duration at each 6-8 W average power and 97-MHz repetition rate at 1030-nm central wavelength. We confirm its suitability for high-resolution spectroscopy in free-running operation by detecting the absorption spectrum of acetylene within 1 millisecond.

We present frequency up- and down-conversion of an Yb-fiber based ultrafast electro-optic (EO) frequency comb. The repetition rate of the EO comb is continuously tunable across 11-18 GHz and a frequency divider further extends the tunability over multiple octaves down to 1 GHz. Burst-mode operation is also demonstrated, showing the potential for flexible operation in the temporal domain. Furthermore, second- and forth-harmonic generation, as well as an optical parametric oscillator have been realized based on the EO comb, extending the flexible GHz pulses to other spectral regions.

CEO-frequency dynamics of a 10-GHz straight-cavity laser modelocked via cascaded quadratic nonlinearities

We show that the power-dependent self-frequency shift introduced by cascaded quadratic nonlinearities couples via the intracavity group delay dispersion to the carrier-envelope offset (CEO) frequency, enabling its control over a wide frequency range.

We report on 100-W 132 MHz Yb:fiber amplifier seeded by a low noise all-polarization maintaining (PM) nonlinear amplifying loop mirror (NALM) oscillator, operating in the near zero-dispersion regime. We tune the laser spectrum to match it to different applications while keeping the noise properties and power performance of the system.

ETH Zurich, Switzerland
We report a novel multiheterodyne relative timing jitter detection measurement and apply it to a single-cavity single-mode-diode pumped dual-comb laser. The inherent passive mutual coherence of the two frequency combs leads to a low relative timing jitter of 7.5 fs [100 Hz, 100 kHz].
