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 ...

However, [Ben Krasnow] stumbled upon a different method entirely when tinkering with a UV laser. The effect is subtle, but remains visible for several minutes. The laser in question was a MNL100 ...
