Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...

In International Journal of Extreme Manufacturing, a new laser machining method that dynamically adapts its beam shape is proposed to fabricate microgrooves with ...

Cholesteric liquid crystal layers aid in electric generation without loss of clarity, according to Science Daily.

An international research team has established a blueprint to arrange complex, knot-like patterns of light, called hopfions, into crystals that repeat across both space and time. The technique uses ...

"Diffraction effects and polarization-related reflections make it difficult to control how energy is distributed during ablation," says Prof. Shaolin Xu, a laser manufacturing expert at SUSTech and ...
