Microfabrication of structures by laser light in metal-doped glasses

摘要: Abstract The direct laser recording of light structures on the surface and in bulk novel, metal-doped, glasses is demonstrated. We record both two- three-dimensional these materials. structure an intensity distribution light, which can take form a focused beam to microlenses, moving draw lines sub-micron width or interference pattern write periodic structures. Experiments were performed containing either Cu 2+ Ag + ions sub-surface layer, are reduced atoms via reduction hot hydrogen atmosphere. materials investigated using cw pulsed over wide range pulse lengths peak intensities at various wavelengths from UV IR. recorded characterized optical microscopy, atomic force microscopy diffraction. mechanisms responsible for sensitivity glass radiation have been theoretically experimentally. able demonstrate control how absorbed by nanoparticles glass, temperature varies as function cluster size, wavelength duration, matrix effected energy randomly distributed clusters. For we studied, results local melting surrounding nanoparticle then leads mass transfer heat kinetics material. This turn aggregation motion allows light. growth clusters their coalescence has measured.
