Abstract: Theoretical and experimental studies of thermal self-defocusing and self-focusing CW laser beams in liquids and solids are given. An analytical theory of thermal self-actions, including ...

In his best runs he managed to draw lines with a width of about 100 nanometers, which is seriously impressive for such a relatively simple setup. These e-beam lithography experiments follow on ...

Hisense just unveiled an all-new 4K laser TV, dubbed the L9Q, as part of its CES 2025 product lineup. It's an ultra short-throw projector offering key upgrades over its predecessor, the Hisense L9H.

Spatial coherence means that there is a well-defined beam with well-defined phase across it. For many lasers, the divergence of the laser beam is ... Here, we therefore test them against the ...

The Sonos Arc Ultra and the Sonos Beam 2 are sleek soundbars designed to elevate your home theater experience, but they differ in key ways. Firstly, the Sonos Arc Ultra is significantly larger ...
