Experiments on large bubbles may put to rest one of the mysteries surrounding the emission of light by bubbles in water.

Pairs of atomic-scale images made from photoelectron diffraction with circularly polarized light can be merged into a stereoscopic, 3D view.

A new technique gives high-resolution images of wave fronts inside microscopic structures used to manipulate light.

Physicists have used an artificial aurora to illuminate a layer of the ionosphere that has been difficult to observe.

Researchers have demonstrated a new way to make high frequency coherent light. A similar process could lead to a compact source of coherent x rays.

A new scheme allows measurements of optical frequencies as accurate as those of the best labs in the world, using only a single laser.

Under special conditions, pulses of light can outpace light waves in a vacuum.

Physicists have demonstrated amplification with electron-photon half-breeds called polaritons, suggesting the possibility of a new type of laser.

The reactions that lead to nuclear power or an atomic blast can now be initiated with laser light, allowing researchers to run new types of nuclear physics experiments.

Physicists have selectively broken certain bonds in a molecule while avoiding others in the most precisely controlled bond breaking ever achieved.

A physicist has invented a technique for identifying very small numbers of molecules using spectroscopy.

A team of physicists has completed the first detailed analysis that explains the surprising ability of light to transmit through very small holes.

Physicists have developed a system that emits single photons on a precise schedule.

Physicists have amplified an image without adding any additional background noise to it.

Researchers have caused ‘matter waves’ to immitate x-rays by diffracting them through ‘crystals of light’.

Using a gas of hot rubidium researchers slowed light signals to 90 m/s without using a Bose-Einstein condensate.
