We demonstrate a two-crystal mid-infrared dual-wavelength optical parametric oscillator, synchronously pumped by a high power femtosecond Yb:fiber laser. The singly-resonant ring cavity, containing two periodically poled lithium niobate crystals, is capable of generating two synchronized idler wavelengths, independently tunable over 30 THz in the 2.9 4.2 μm wavelength region, due to the cascade...
We demonstrate a method for time gating the standard heralded continuouswave (cw) spontaneous parametric down-converted (SPDC) single photon source by using pulsed pumping of the optical parametric oscillator (OPO) below threshold. The narrow bandwidth, high purity, high spectral brightness and the pseudo-deterministic character make the source highly suitable for light-atom interfaces with ato...
We demonstrate a method for time gating the standard heralded cw spontaneous parametric downconverted single-photon source by using pulsed pumping of an optical parametric oscillator below threshold. The narrow bandwidth, high purity, high spectral brightness, and pseudodeterministic character make the source highly suitable for light-atom interfaces with atomic memories.
We show experimentally that parametric interaction can induce a cooperative oscillation of non-simultaneously resonant transverse modes in an optical parametric oscillator. More generally, this effect is expected to occur in any spatially extended system subjected to boundary conditions where nonlinear wave mixing of two nonresonant spatial modes can generate a resonant oscillation.
