TL;DR: In this article, the use of optical fiber for optical parametric chirped pulse amplification to amplify sub-picosecond pulses was demonstrated for the first time, and the peak power of the signal was amplified from 93 mW to 10 W.
Abstract: We experimentally demonstrate, for the first time to the best of our knowledge, the use of optical fiber for optical parametric chirped pulse amplification to amplify subpicosecond pulses. We use this system to amplify a subpicosecond signal at 1595 nm generated by a fiber-optical parametric oscillator. The 750-fs signal from the oscillator output is stretched to 40 ps, amplified by an all-fiber optical parametric amplifier and then compressed to 808 fs. The peak power of the signal is amplified from 93 mW to 10 W.

TL;DR: An optical parametric oscillator that is pumped by population-trapped atoms that are prepared with maximum coherence that is based on the use of an effective nonlinear susceptibility that is of the same order as the linear susceptibility is described.
Abstract: We describe an optical parametric oscillator that is pumped by population-trapped atoms that are prepared with maximum coherence. The oscillator is based on the use of an effective nonlinear susceptibility that is of the same order as the linear susceptibility. Because the parametric gain is obtained in a single coherence length, the gain bandwidth can exceed the degenerate frequency. In Pb vapor the calculated gain is maximized at 1.88 µm and has a bandwidth of ∼7500 cm-1.

TL;DR: A pulsed doubly resonant optical parametric oscillator that uses an original entangled-cavity geometry that displays single-frequency operation, a high repetition rate, low threshold, and wide tuning in the mid-infrared.
Abstract: We report a pulsed doubly resonant optical parametric oscillator that uses an original entangled-cavity geometry. This compact source (total volume of 1 L, including the pump laser) displays single-frequency operation (linewidth, 10 kHz, low threshold <10 µJ, and wide tuning in the mid-infrared. These properties qualify pulsed doubly resonant optical parametric oscillators as powerful tools for applications in such fields as nonlinear spectroscopy, lidar, and pollutant detection.

TL;DR: In this article, the coupling mechanism between a jet-slot oscillator and a deep cavity resonator as well as the effect of feedback control on this coupling mechanism are investigated experimentally, and it is shown that the resonant oscillations can be attenuated by a maximum amount ranging from 11 to 13dB.

TL;DR: In this paper, the noise spectra of the in-phase and quadrature-phase components of the signal and idler fields of a nondegenerate optical parametric amplifier are calculated.
Abstract: Noise spectra of the in-phase and quadrature-phase components of the signal and idler fields of a nondegenerate optical parametric amplifier are calculated. It is shown that, as is suggested by the operator Manley-Rowe relations, the external in-phase (amplitude) fluctuations of the signal and idler fields are correlated in the frequency region lower than the signal and idler cavity bandwidths. If the idler photon flux is continuously measured and the photocurrent fluctuations are fed back to control the pump intensity, the signal output will feature an amplitude noise spectral density reduced to below the standard quantum limit (amplitude squeezing) in the frequency region below the feedback loop and signal and idler cavity bandwidths. An all-optical realization of such a negative-feedback parametric oscillator is presented. It is also shown that a nondegenerate parametric amplifier with idler measurement feedback can add a fixed number of photons to a photon-number state.
