U.S. Naval Research Laboratory (NRL) scientists successfully demonstrated a dual-use laser system capable of wirelessly ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

Shopping for a printer largely boils down to choosing between inkjet and laser. Both put text and images onto paper, which seems straightforward enough, but they differ in how they do it. Which you ...

In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade. The ...

NTT Inc. and Mitsubishi Heavy Industries Ltd. (MHI) conducted an optical wireless power transmission experiment using a laser beam to wirelessly transmit energy over a distance of one kilometer. By ...

Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can ...

Laser cataract surgery involves using a laser beam to make incisions in the eye and break up a cataract. It offers an alternative to traditional surgery, in which surgeons break up a cataract manually ...

Over the following years, prototypes were built, using freely available parts from cell phones and laser printers. A device was patented and demonstrated by a company called Intellectual Ventures, ...
