Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other ...

The Jena-based team, led by Till Walbaum, have used spectral beam combining - a technique also deployed in laser weapons development - to raise the output power of systems emitting light at ...

Scientists at CAS develop compact, solid-state laser system that generates 193-nm coherent vortex beam. Deep UV solid-state laser with ... solid-state laser system capable of generating 193 nm ...

because they struggle to reach the same beam quality and focus at high outputs. With laser diodes, the larger the surface of the active material producing the laser light, known as a resonator ...
