Scientists have found a way to bend lasers — and may use it to bend lightning as well. A team led by Pavel Polynkin of the University of Arizona sent a special sort of laser beam — pulsed instead of ...
When a beam of energetic electrons travels through a plasma, the space charge at the tip of the beam knocks electrons from the ions in the plasma, leaving the ions with a larger positive charge. If ...
A pioneering method has emerged for manipulating laser beams using sound waves alone. These days, powerful laser beams are essential in scientific research, from particle accelerators to nuclear ...
Gilson is part of the Virtual National Laboratory for Heavy-Ion Fusion, a partnership between the PPPL, E.O. Lawrence Berkeley Lab and Lawrence Livermore National Laboratory in California. According ...
SELF-BENDING light beams capable of turning a corner like a boomerang are darting around an optics laboratory in France. The beams are just a few micrometres across, and could improve the way in which ...
