Journal ArticleDOI
Sideband generation using strongly driven raman coherence in solid hydrogen
TL;DR: The Raman coherence prepared with two coaxial single-mode lasers beats with multimode laser radiation with very broad bandwidth and efficiently replicates the broadband nature to the Raman sidebands without the restriction of phase matching.
Journal ArticleDOI
Octave-spanning Raman comb with carrier envelope offset control.
TL;DR: It is shown that in both the temporal and spectral domains, locking the dual frequencies on a single laser cavity provides control of the carrier-envelope-offset frequency at integer multiples of the free spectral range of the laser cavity.
Journal ArticleDOI
Self-Induced Phase Matching in Parametric Anti-Stokes Stimulated Raman Scattering
TL;DR: In this article, it was shown that phase matching in a parametric process can be self-induced without the stringent restriction of the medium, and that the phase matching can be achieved by strong coupling between radiation fields and medium spontaneously established through the stimulated Raman scattering process.
Journal ArticleDOI
Frequency comb generation at terahertz frequencies by coherent phonon excitation in silicon
TL;DR: By exciting few-cycle femtosecond laser pulses at 397 nm in near-resonance with the direct bandgap of silicon, the authors experimentally demonstrate coherent phonon generation in silicon at a fundamental frequency of 15.6 THz and all-optical >100 THz frequency comb generation.
