Scientists develop a technique to dynamically curve a photon jet

Scientists at Tomsk Polytechnic University jointly with international colleagues have found a simple technique to dynamically curve a photonic jet, turning it into a photonic hook. The method was published in Optics Letters. ...

Upgraded X-ray laser shows its soft side

The second phase of a major upgrade project is now online at the Linac Coherent Light Source (LCLS), the pioneering X-ray free-electron laser at Department of Energy's SLAC National Accelerator Laboratory. On September 12, ...

Engineers create micron-scale optical tweezers

In 2018, one-half of the Nobel Prize was awarded to Arthur Ashkin, the physicist who developed optical tweezers, the use of a tightly focused laser beam to isolate and move micron-scale objects (the size of red blood cells). ...

Fastest star ever seen is moving at 8% the speed of light

In the center of our galaxy, hundreds of stars closely orbit a supermassive black hole. Most of these stars have large enough orbits that their motion is described by Newtonian gravity and Kepler's laws of motion. But a few ...

Laser beams reflected between Earth and moon boost science

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced today, in collaboration ...
