TL;DR: In this article, the impact of the first asymmetric liquid sloshing mode, represented by an equivalent pendulum, and the elastic structural dynamics is examined in the neighborhood of simultaneous occurrence of parametric and internal resonance conditions.

TL;DR: In this paper, the authors reported the generation of tunable light pulses with durations as short as 65 fs by pulsed synchronous pumping of a singly resonant optical parametric oscillator.
Abstract: We report the generation of tunable light pulses with durations as short as 65 fs by pulsed synchronous pumping of a singly resonant optical parametric oscillator. The measured wavelength dependence of the pulse duration provides evidence for self-compression by means of chirp reversal of the idler pulses and normal dispersion of the optical parametric oscillator cavity elements.

TL;DR: In this article, the evolution of a quantum electromagnetic field in a 1D cavity (Fabry-Perot interferometer) is studied in the case when an ideal wall performs small harmonic oscillations at a frequency coinciding with the intermode interval in the equidistant eigenfrequency spectrum of the unperturbed field.
