Frequency comb generation via cascaded second-order nonlinearities in microresonators
, 2019 Optical frequency combs are revolutionising modern time and frequency metrology. In the past years, their range of applications has increased substantially, driven by their miniaturisation through microresonator-based solutions. The combs in such devices

Ultrafast response of harmonic mode-locked THz lasers [PDF]
Novel In-Plane Semiconductor Lasers XX, 2021 The use of fundamental modelocking to generate short terahertz (THz) pulses and THz frequency combs from semiconductor lasers has become a routine affair, using quantum cascade lasers (QCLs) as a gain medium. Here, using time-resolved THz techniques, we show the first of demonstration harmonic injection and mode- locking in which THz QCLs are modulated

Topological Coherent Modes in Trapped Bose Gas
, 2005 The report reviews the problem of topological coherent modes, which are nonlinear collective states of Bose-condensed atoms. Such modes can be generated by means of alternating external fields, whose frequencies are in resonance with the transition ...

Theory of passive harmonic mode-locking using waveguide arrays
Optics Express, 2008 A comprehensive theoretical treatment is given of the phenomenon of harmonic mode-locking in a laser cavity mode-locked by the nonlinear mode-coupling behavior in a waveguide array. The theoretical model completely characterizes oscillatory instabilities and the transition from M to M+1 pulses as a function of increased gain.

Laser à fibre verrouillé en phase à haute cadence [PDF]
, 2011 We investigate different ways to considerably increase the repetition-rate of passively mode-locked fiber lasers. We first report the harmonic mode-locking of a double-clad fiber laser passively mode-locked through nonlinear polarization rotation.
