Frequency conversion based on three-wave parametric solitons [PDF]

, 2010
Parametric three-wave mixing in quadratic nonlinear crystals provides a versatile means of achieving widely tunable frequency conversion of laser light, thus permitting a substantial extension of the wavelength coverage of laser sources across broad ...

Observation of Three-Photon Spontaneous Parametric Down-Conversion in a Superconducting Parametric Cavity

Physical Review X, 2020
Spontaneous parametric down-conversion (SPDC) has been a key enabling technology in exploring quantum phenomena and their applications for decades. For instance, traditional SPDC, which splits a high-energy pump photon into two lower-energy photons, is a

Efficient generation of few-cycle pulses beyond 10 μm from an optical parametric amplifier pumped by a 1-µm laser system

Scientific Reports, 2022
Nonlinear vibrational spectroscopy profits from broadband sources emitting in the molecular fingerprint region. Yet, broadband lasers operating at wavelengths above 7 μm have been lacking, while traditional cascaded parametric frequency down-conversion ...

Imaging high-dimensional spatial entanglement with a camera [PDF]

, 2012
The light produced by parametric down-conversion shows strong spatial entanglement that leads to violations of EPR criteria for separability. Historically, such studies have been performed by scanning a single-element, single-photon detector across a ...

Towards spontaneous parametric down-conversion at low temperatures

EPJ Web of Conferences, 2017
The possibility of observing spontaneous parametric down-conversion in doped nonlinear crystals at low temperatures, which would be useful for combining heralded single-photon sources and quantum memories, is studied theoretically.

Generation of Entangled Photons by A Short Coherence Length Violet Diode Laser

Diyala Journal of Engineering Sciences, 2013
Pumping a BBO crystal by a violet diode laser with a wavelength of (405  nm) output power of (24 mW) and a line width of (3nm) was employed to generate entangled  photons with a wavelength of 810 nm by achieving type II phase matching conditions.
