Researchers have demonstrated an innovative technique for increasing the intensity of lasers. This approach, based on the compression of light pulses, would make it possible to reach a threshold ...

Applied physics bridges the gap between physics, engineering, and other sciences. While engineers solve well-defined problems, applied physicists focus on applying physics interdisciplinarily. At ...

Since the advent of lasers, researchers have strived to build an acoustic equivalent — devices that can amplify and emit sound waves at a single frequency. Kerry Vahala and his group at the California ...
