optical physics

Researchers have shown how to effectively transform one material into another using a finely shaped laser pulse.

Sometimes a mirror that reflects 99.9999% of light isn’t good enough.

Three researchers shared the Nobel Prize in Physics for advances in laser physics. The winners include a woman for the first time in 55 years.

The search for exotic new physical phenomena is being led by huge experiments like the Large Hadron Collider. But at the other end of the spectrum lie tabletop experiments — small-scale probes of hidden dimensions, dark matter and dark energy.

Researchers are making progress toward a “perfect lens” that will be able to resolve an organelle assembling a protein or a virus attacking a cell.
