Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Researchers have developed a novel, lab-tested design for a laser-driven light sail that exhibits self-stabilization capabilities. This innovative design mitigates beam misalignment, a critical ...

LED headlamps are only just trickling onto the market -- mostly on high-end cars -- but now it seems a certain German automaker has plans for laser headlamps. "Laser light is the next logical step in ...

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of ...

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...
