Astronomers using the MeerKAT telescope discovered a hydroxyl megamaser in a galactic merger 8 billion light-years away, amplified by gravitational lensing and operating at radio wavelengths.

Physicists at the University of Colorado Boulder have demonstrated a new type of vacuum ...

Physicists at the University of Colorado Boulder have demonstrated a new kind of vacuum ultraviolet laser that is 100 to 1,000 times more efficient than existing technologies of its kind. The ...

Scientists have successfully tested a material design for light sails using photonic crystals that could achieve 20% the speed of light ...

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 ...

When we first heard the term “random laser,” we did a double-take. After all, most ordinary sources of light are random. One defining characteristic of a traditional laser is that it emits coherent ...

Anthony Fiorito, a senior engineering physics major at Florida Polytechnic University, was published as first author of a study that found that when infused with a specific dye, peacock feathers can ...

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 ...
