Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. Known as “spacetime wave packets,” these lasers follow different rules of refraction ...

Researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels. The findings could have huge implications for optical ...

All the latest science news on light refraction from Phys.org. Find the latest news, advancements, and breakthroughs.

The precision of the wavefront refraction is 25 times greater than a phoropter refraction because it can measure 1/100th of a diopter (3.01 D, 3.02 D and so on, up to 3.99 D), rather than just one ...
