Last week, four lasers were projected into the sky above the European Southern Observatory (ESO) Paranal site in Chile. The ...

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 ...

A team at the University of Stuttgart has engineered a compact short-pulse laser that achieves up to 80% efficiency—far ...

Dynamic switch: a switchable metasurface, tuned by green laser light, can block or transmit particular wavelengths of light. (Courtesy: CMP/ORC Southampton University) A new type of optical ...

Trapped: a look inside the Stark decelerator used in the experiment. The molecules fly through a tube formed by 4 mm-diameter rings, which can be seen in the centre of the image. (Courtesy: Steven ...

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 ...

Laser beams are usually hard to miss, but a new laser is notable for its lack of light. Steven Cundiff at the University of Colorado in Boulder and his colleagues built the device by modifying a ...

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 ...

Scientists Arthur Ashkin, Gerard Mourou and Donna Strickland have won the 2018 Nobel Prize for Physics for breakthroughs in the field of lasers used for surgery as well as scientific study. Arthur ...

Engineering physics blends concepts from engineering, physics, and math in an effort to bridge the gap between theoretical science and practical engineering. Engineering physicists focus on research ...
