While lasers amplify the power of light, ‘sound lasers’ achieve the same result with phonons instead of photons. A new study from researchers in China details a new sound laser that they claim is the ...

We've been following the quest for the world's best speakers for some time but remarkably, there's still room for improvement. A key issue that plagues proper sound reproduction (and thus its ...

What happens when you hurl molecules faster than sound through a vacuum chamber nearly as cold as space itself? At the University of Missouri, researchers are finding out—and discovering new ways to ...

The optical laser has grown to a $10 billion global technology market since it was invented in 1960, and has led to Nobel prizes for Art Ashkin for developing optical tweezing and Gerard Mourou and ...

The quest for ever more realistic sound reproduction seems set to move to a whole new level. Traditional microphones convert sound to electrical signals by measuring the deflections that sound ...

Lasers amplify light, masers amplify microwaves, and now, from France, comes the saser: a supercool glass rod that amplifies sound. Lasers have become ubiquitous: they read the prices of our groceries ...

Biomedical engineers are now able to take a live, holistic look at the inner workings of a small animal with enough resolution to see active organs, flowing blood, circulating melanoma cells and ...

These high-powered sound beams have multiple uses. (Representational Pic) Scientists in China have created an unprecedentedly bright laser that shoots particles of sound instead of light. According to ...
