Optical Two-Tone Time Transfer
Jonathan D. Roslund, Abijith S. Kowligy, Junichiro Fujita +5
Sub-picosecond timing synchronization can enable future optical timekeeping networks, including coherent phased array radar imaging at GHz levels, intercontinental clock comparison…
Broadband ultraviolet-visible frequency combs from cascaded high-harmonic generation in quasi-phase-matched waveguides
Jay Rutledge, Anthony Catanese, Daniel D. Hickstein +3
High-harmonic generation (HHG) provides short-wavelength light that is useful for precision spectroscopy and probing ultrafast dynamics. We report efficient, phase-coherent harmoni…
Fully phase-stabilized 1 GHz turnkey frequency comb at 1.56 m
Daniel M. B. Lesko, Alexander J. Lind, Nazanin Hoghooghi +7
Low noise and high repetition rate optical frequency combs are desirable for many applications from timekeeping to precision spectroscopy. For example, gigahertz repetition rate so…
A six-octave optical frequency comb from a scalable few-cycle erbium fiber laser
Daniel M. B. Lesko, Henry Timmers, Sida Xing +3
A compact and robust coherent laser light source that provides spectral coverage from the ultraviolet to infrared is desirable for numerous applications, including heterodyne super…
Mid-infrared frequency combs at 10 GHz
Abijith Kowligy, David Carlson, Daniel Hickstein +5
We demonstrate mid-infrared (MIR) frequency combs at 10 GHz repetition rate via intra-pulse difference-frequency generation (DFG) in quasi-phase-matched nonlinear media. Few-cycle…
All-fiber frequency comb at 2 μm providing 1.4-cycle pulses
Sida Xing, Abijith S. Kowligy, Daniel M. B. Lesko +2
We report an all-polarization-maintaining fiber optic approach to generating sub-2 cycle pulses at 2 μm and a corresponding octave-spanning optical frequency comb. Our configuratio…
