This book gathers the latest research from around the globe on the subject of lasers and optics research. Topics discussed include selective laser sintering/melting and laser erosion with Nd: YAG lasers; pulsed laser deposition of nanostructured oxides; high efficiency diode pumped Nd: YAG lasers and in the micro- and nano-structuring of solids; features of polarisation and intensity profile of output beam from a dual-crystal solid-state laser system and context-sensitive recurrent filters for visual motion analysis.
