Rapid pulses of laser light that bend without the aid of a lens could be used to more efficiently monitor air pollution, a new study reports.
... found a way of protecting quantum systems against noise using adaptively ‘shaped` pulses of laser light. Quantum systems are notoriously fragile as interactions with their surroundings disturb them ...
... which use the principle of random light scattering as an integral part of the laser operation. In conventional lasers light is trapped between two highly reflecting mirrors where it is amplified by ...
... vocal-cord tissue. The use of specific wavelengths of laser light to target blood vessels was originally ... been recognized for his 2006 use of pulsed-KTP laser to treat Steven Tyler of the rock band ...
... and surgeons carry out medical operations with laser beams. Nevertheless there are numerous unusual kinds of laser light that are still largely unexplored, one of them being Diffusive Random Lasers.
Researchers at Chalmers University of Technology, in Sweden have reported that a single laser pulse can create complex, ordered nanostructure systems. This previously unobserved phenomenon has been ...
... maintain a consistent distance between the bead and the surface of the microchip. If this distance changes, the laser light is focused in different ways across the surface and the resulting pattern ...

To develop the miniature laser-surgery system, Ben-Yakar worked ... nano-scale magnifying lenses, increasing the laser light reaching cells by at least an order ...
When lasers illuminate material it usually warms up. Therefore laser beams are, for example, used for cutting sheet steel, for welding or even as scalpels. But this effect can also be reversed...
... -killing chemicals when lit by a specific kind of laser light. Michael Wilson led a team ... researchers emits 'near-infrared' light, which is known to be capable of producing heat. However, as Wilson ...
Tiny collimator reduces divergence of light from semiconductor lasers
... fluorescence lifetimes. This could lead to the development of a new diagnostic method whereby laser light could be used to directly recognise certain genetic sequences without, for example, having to ...
... the CU team describes how they shot a molecule of dinitrogen tetraoxide, or N2O4, with a short burst of laser light to induce very large oscillations within the molecule. They then used a second laser ...
... . Exhale into the device, and molecules in your breath that could indicate disease absorb rays of laser light. A computer diagnoses you by matching the absorption patterns to a library of chemical " ...
