Scientists at CAS develop compact, solid-state laser system that generates 193-nm coherent vortex beam. Deep UV solid-state laser with compact setup generates a vortex at 193 nm. Deep ultraviolet (DUV ...

The researchers also introduced a spiral phase plate to the 1,553-nm beam before frequency mixing, resulting in the generation of a vortex beam carrying orbital angular momentum. This marks the ...

A major scientific breakthrough could change how we understand and control ionization — the process where atoms lose ...

Paulson School of Engineering and Applied Sciences (SEAS) report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to ...
