We demonstrate the use of kW class, high energy pulsed nanosecond lasers for surface cleaning applications. A hybrid ablation-detachment process allows removal rates of semi-transparent paint from primer at 40,000 mm3 /kW.min. The process shows a thr

Here we present a silicon based, micro-machined fluidic device for terahertz frequencies, fabricated using standard lithographic and micro-machining processes in a cleanroom environment. Designed for use in a conventional transmission terahertz time-

We show how a photonic crystal prism can be used to filter a broadband terahertz beam using the properties of negative and positive refraction. Different components of a broadband beam incident on the structure may be positively or negatively refract

Superfluorescence (SF) is the emission from a dense coherent system in population inversion formed from an initially incoherent ensemble. This is characterized by an induction time (${\ensuremath{\tau}}_{\mathrm{D}}$) for the spontaneous development

We demonstrate how micromachined photonic crystals can be used to negatively refract terahertz frequency light. The photonic crystals, which are constructed from conventional dielectric materials, manipulate the incident beam via interaction with the

Steady-state and time-resolved photoluminescence have been used to investigate the optical properties of bilayer and blend films made from poly(9,9-dioctyl-fluorene-2,7-diyl) (PFO) and poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH PP
