In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow ... casting a visible shadow in the shape of the green laser.

Physicists at the University of Ottawa add an orbital spin to their laser beams to control the movement of electrons in their ...

Deep ultraviolet (DUV) lasers, known for their high photon energy and short wavelengths, are essential in various fields such ...

A new solid-state laser produces 193-nm light for precision chipmaking and even creates vortex beams with orbital angular ...

Knowledge of a laser beam's shape and output-power distribution is critical for optimizing laser performance. Neil Savage summarizes the latest beam-profiling products on the market. People using ...

Discover how Farsoon and beam shaping improve metal additive manufacturing with innovative laser spot configurations and ...

The tool, known as MINFLUX, involves attaching a small organic fluorophore to a protein then exciting the complex with a donut-shaped laser beam. If the protein is anywhere beneath the ring, the ...

His first attempts either blew right through the film or did absolutely nothing, but eventually he had the bright idea to move the laser farther from the LDPE. This put the beam out of focus ...

To realize STED in two dimensions, the diffraction-limited point spread function (PSF) is reduced to a subdiffraction-sized PSF by overlaying a donut-shaped laser beam (“STED beam”) onto the ...

We photopolymerize complex-shaped particles within glass cells consisting of a ... model LS3Z2, 200 Hz). The pulsed laser beam is first passed through a half-wave plate and subsequently through a Glan ...

Laser beam shaping systems such as nLIGHT offer a step-function in laser productivity over the Gaussian laser shape that is standard across the powder bed fusion (PBF) additive manufacturing ...
