Scientists have cracked a century-old physics mystery by detecting magnetic signals in non-magnetic metals using only light and a revamped laser technique. Previously undetectable, these faint ...

Washington State University. (2021, December 10). Atom laser creates reflective patterns similar to light. ScienceDaily. Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2021 / 12 ...

This fractal pattern was created with a laser light. (Image credit: Wits University) Nature is brimming with beautiful patterns, like the seemingly complex shapes of snowflakes, coastlines, clouds ...

Theoretical calculations hint that, in addition to these 2-D patterns, laser light should also display 3-D fractals. Finding those patterns will be scientists’ next challenge.

A technique developed by Princeton engineers allows the easy creation of nano-scale patterns on uneven surfaces and without the normal requirements of a vibration and oxygen-free environment.

The laser produces infrared light in a specific OAM mode, and Feng says that the laser has a sideband suppression ratio of approximately 40 dB. This is a measure of the quality of the laser light, ...

An atom laser flowing from top to bottom makes a “caustic”, a refracted pattern like that often made by light, as it encounters an obstacle.
