This is a sequence of continuously captured images showing the progression of Baily’s beads at third contact during the 2023 annular eclipse ... all the fast-moving beams that lit up the ...

The Xreal Beam Pro is a good idea on paper, which is fun to use and inexpensive for the pleasure. If you learn the ways of the AR power user, you can turn this into a nifty little spatial computer.

Multi-focusing, array of optical spots, annular beams, top hat beams, optical vortices, petal-like beams, bifocal and multifocal lenses, bottle and extended-focus beams lenses, etc. are some of the ...

In Aachen, Germany, the institute’s engineers have developed a new optical system with glass substrates and an arc torch which unites metal shielding gas (MSG) welding and laser material deposition ...

Their design has three segments that, collectively, efficiently align and transform a conventional Gaussian beam into an annular beam and then, finally, a Bessel beam of the desired order and OAM ...

To overcome this issue, scientists of the Extreme Light Infrastructure Attosecond Pulse Light Source (ELI ALPS) shaped the laser beam to an annular shape, and combined with proper experiment ...

Over the years, one-element and two-element refracting systems have been proposed to achieve beam shaping where Gaussian and annular-Gaussian beam profiles were transformed to uniform beams, as well ...
