Investigation of the microstructure change due to phase transition in nanosecond pulsed laser processing of diamond (2017)
Journal Article
Experiments and theory are employed to investigate the thermal damage induced by infra-red nanosecond pulses in atmospheric air into a boron-doped diamond target. Micro-Raman spectroscopy, Transmission Electron Microscopy (TEM) analysis and surface t...

New models for energy beam machining enable accurate generation of freeforms (2017)
Journal Article
We demonstrate that, despite differences in their nature, many energy beam controlled-depth machining processes (e.g. waterjet, pulsed laser, focused ion beam) can be modelled using the same mathematical framework – a partial differential evolution e...

Waterjet and laser etching: the nonlinear inverse problem (2017)
Journal Article
In waterjet and laser milling, material is removed from a solid surface in a succession of layers to create a new shape, in a depth-controlled manner. The inverse problem consists of defining the control parameters, in particular, the two-dimensional... Read More about Waterjet and laser etching: the nonlinear inverse problem.
A study of surface swelling caused by graphitisation during pulsed laser ablation of carbon allotrope with high content of sp ³ bounds (2017)
Journal Article
Experiments and theory are employed to investigate the laser ablation of boron doped diamond and tetrahedral amorphous carbon using nanosecond pulses. For a single pulse at low values of fluence, the laser induces a swelling of the surface due to gra...
