Ultra-Cold Neutrons is the complete, self-contained introduction and review of the field of ultra-cold neutron (UCN) physics. It is suitable as an introduction to the field for research students, as a useful compendium of results and techniques for researchers and is of general interest to non-specialists in other areas of physics such as neutron, atomic and fundamental physics and neutron scattering.
High power fibre laser technology has come of age over the past five years or so, due primarily to developments in fibre design and fabrication and semiconductor pump lasers. Fibre is now emerging as the technology of choice for a wide range of laser applications. Nowhere has the progress been more striking than in terms of the maximum continuous wave output power achievable from a single-mode fibre laser. Up until the start of 2001 the maximum reported output power from such a laser was ~110W. However, since then the reported power levels have risen rapidly and steadily such that by late 2006 values as high as 2.5kW were achieved with great prospects for further extension to the 10kW regime. Far higher power levels than this should be achievable in due course using beam combination technology. Fibre lasers are thus consequently now st...

We review recent advances in the development of novel fibre components for short pulse generation and manipulation. In particular, we describe the development of high power, high pulse energy fibre sources based on novel doped fibre designs and present our latest results on continuous dispersion tapered fibre fabrication and its application to high capacity soliton communications
The successful future implementation of high speed optical networks and optical processing schemes is dependent on the continued development of a wide range of high performance optoelectronic devices and subsystems. In this presentation we review recent advances in the development of fibre based components that could prove attractive for use in future all-optical processing systems. The development of materials with large, fast optical nonlinearities is of great interest for many all-optical processing schemes. We describe recent progress at the ORC in the development of glass/fibre devices with increased (relative to conventional silica fibre) optical nonlinearities and which should allow for the fabrication of compact nonlinear fibre devices. In addition, we report the discovery of a new, massive optical nonlinearity associated with...
