Water molecules flip their orientation before splitting into hydrogen and oxygen. These acrobatics require significant energy ...

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 ...

Researchers in Nikolaus Rajewsky's lab at Max Delbrück Center combined high-resolution, single-cell spatial technologies to ...

In the 1960s, physicists showed how light could interact with itself in intriguing ways thanks to a process known as second-harmonic generation. In the right kind of material, two photons of a certain ...

A new gating scheme based on polarization control and second-harmonic generation is greatly simplifying the production of isolated attosecond pulses. Attosecond pulses — flashes of light lasting ...

(a) Schematic representation of the experiment. Local SHG signal is enhanced by irradiating an infrared laser pulse into the plasmonic nanogap between the gold tip and the gold substrate.

In situ diagnosis Multiphoton microscopy combines second- and third-harmonic generation (SHG and THG), along with two- and three-photon excitation, to rapidly visualize molecular and structural ...

Researchers developed a scalable fabrication process using soft nanoimprint lithography to create lithium niobate metalenses, ...
