Quantum plasmas. Quantum effects become important under extreme conditions, and a newly developing field of "quantum plasmas" is motivated by two different extremes for ionized systems. One is in very small electronic devises, where electrons carrying the currents become wave-like with a wavelength comparable with the size of the device. The other is in the extremely intense optical light spots now available by focusing high-power lasers. In this project we propose to take a leading role in the ....Quantum plasmas.

Summary
Advanced Microwave Facility for Quantum-Atom Optics. Atoms can be controlled using light in visible and infra-red regions, as well as electromagnetic waves of longer wavelength in the microwave (MW) and radiofrequency (RF) part of the spectrum. We presently use optical radiation to control atoms at the quantum level where they can behave like waves and can interact with light to store and manipulate information. The MW and RF facility will extend our abilities and enable more complete control of ....Advanced Microwave Facility for Quantum-Atom Optics.

We presently use optical radiation to control atoms at the quantum level where they can behave like waves and can interact with light to store and manipulate information. The MW and RF facility will extend our abilities and enable more complete control of the atoms, which will help us develop the first generation quantum technology. This will enable the creation of quantum devices such as atom lasers, atom interferometers and quantum information networks for communication and ultra-sensitive measurement applications.Read moreRead less

We have recently made significant advances in development of all-solid-state intracavity Raman lasers generating multiwatt average powers in the near infrared and (by frequency doubling) visible spectrum, with important applications in biomedicine and remote sensing. A new generation of Raman crystals, especially tungstates, offer superior optical, mechanical and thermal properties, promising high Raman gains and choice of Stokes frequency shift. The project will investigate a range of key issues for these materials including control of the Stokes wavelength, associated polarisation control, and pump-resonator configurations giving maximum Raman laser power and efficiency. The project will lead to state-of-the-art source technology with outstanding prospects for commercialisation and practical application.Read moreRead less

The aims of this project are to develop detailed finite-difference time-domain numerical models of active photonic crystal structures, and to use them to optimise the design and performance of photonic-crystal-based devices, especially micro-cavity lasers. Photonic crystal microlasers have the potential to provide very efficient and low noise laser sources in micron-sized cavities, however the simplistic structures used to realise these lasers to date provide sub-optimal performance. Innovative designs with improved performance will be developed by tailoring both the optical and thermal properties of planar photonic crystal stuctures. Devices designed during this project will subsequently be fabricated at facilities in France.Read moreRead less
