Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

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 ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

I’m not a smoker, and I don’t carry a lighter around in case anyone needs a light. However, I could totally see myself with a miniature laser lighter. In fact, if you want to build one, feel free to ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

Thin layers of organic molecules can be fabricated over large areas at low cost, and their electrical and optical properties can be chemically tuned with ease. These characteristics make organic ...

A team at Harvard and Technical University of Vienna have invented a new tunable laser that uses a series of rings to smoothly emit many light wavelengths from a single chip. The laser could replace ...
