Thermo-optic dispersion formula for AgGaS2.
The thermo-optic dispersion formula that can be used for good reproduction of the temperature-dependent phase-matching conditions thus far reported in the literature as well as new data for second-harmonic generation of a CO(2) laser and its harmonics at 1.7652-5.2955 microm is presented.
Linear and nonlinear optical properties of AgGaS 2 , CuGaS 2 , and CuInS 2 , and theory of the wedge technique for the measurement of nonlinear coefficients
The refractive indices of the ternary A^{I}B^{III}C_{2}^{VI} semiconductors AgGaS 2 , CuGaS 2 , and CuInS 2 have been measured over the entire range of transparency of these crystals. The optical
Numerical investigation of mid-infrared single-photon generation
Photon-pair creation through parametric downconversion underpins quantum technology for quantum sensing and imaging. Here we numerically study the creation of single photons in the near- and
Direct measurement of heralded single-photon statistics from a parametric down-conversion source
We present a full triple-coincidence analysis of photon-pair states generated by spontaneous parametric down-conversion. By increasing the coherence time of the source with the help of an intracavity
Long-wave infrared generation from femtosecond and picosecond optical parametric oscillators based on orientation-patterned gallium phosphide
Optical parametric oscillators synchronously pumped with 1-µm femtosecond and picosecond lasers are used to generate long-wave mid-infrared radiation using the nonlinear material
Comment on 'Coherence measures for heralded single-photon sources'
A recent Brief Report [Phys. Rev. A 79, 035801 (2009)] investigates two figures of merit for heralded photon sources based on spontaneous parametric down-conversion with a continuous pump, namely,
Tunable Optical Coherence Tomography in the Infrared Range Using Visible Photons
We report a proof-of-concept demonstration of a tunable infrared (IR) optical coherence tomography (OCT) technique with detection of only visible range photons. Our method is based on the
Entangled biphoton source - property and preparation
One of the most surprising consequences of quantum mechanics is the entanglement of two or more distance particles. Even though there are still questions regarding the fundamental issues of quantum
Quantum Spectroscopy of Plasmonic Nanostructures
We use frequency entangled photons, generated via spontaneous parametric down conversion, to measure the broadband spectral response of an array of gold nanoparticles exhibiting Fano-type plasmon
Measurement of nonlinear coefficient and phase matching characteristics of AgGaS/sub 2/
The nonlinear optical characteristics of AgGaS/sub 2/ were investigated by measuring visible parametric fluorescence with a pump wavelength of 600 nm. A value of d/sub 36/ (AgGaS/sub
