Lasers are typically associated with precise beams and high-tech equipment. But the one built by Wang’s team works differently. Called a random laser, it generates light by scattering photons through ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Abstract: The microstructure of a specimen is often characterized by surface roughness during manufacturing and its accurate measurement is the cornerstone of the machining operations. The rapid ...

The article reviews laser processing methods that enhance micro-LED displays, addressing optical challenges and improving ...

Abstract: Photonic crystal (PC) is an excellent solution to realize a surface-emitting quantum cascade laser. The size of photonic crystal array has a severe relevance with both cost and heat ...

We collected a multi-view, multi-detector SEM dataset covering various samples with diverse geometric characteristics. The dataset includes complex microstructures fabricated using the two-photon ...

Laser material processing uses high-intensity light beams in material fabrication. This can include cutting, engraving, drilling or welding metals. It can also include cleaning materials with lasers.
