Depending on how they’re cut, crystals of these sorts have non-linear optical properties like second-harmonic generation, which combines two input photons into a single output photon with twice ...

A research group recently discovered the disappearance of nonreciprocal second harmonic generation (SHG) in MnPSe₃ when integrated into a two-dimensional (2D) antiferromagnetic MnPSe₃/graphene ...

The optical properties of liquid crystals have been a subject of study for many years now, with previous papers investigating second harmonic generation in ferroelectric smectic liquid crystals being ...

Recently, however, scientists at Colorado State University employed 3D second harmonic generation achieved frame rates over 8,000 times faster than is possible with current nonlinear optical ...

Operating over the industrial temperature range of -40 to 85ºC, the device suppresses the second harmonic to better than -12 dBc. The robust V600ME45-LF octave tuning VCO comes in the company's ...
