摘要: In this paper, the spatial and spectral properties of colour centres produced in LiF single crystals by ultrashort high intensity laser pulses are reported. The emission spectra were measured conventionally also confocal microscopy. A large amount F that gave rise to aggregates such as F2, F4, F2+ F3+ could be identified, showing a microscopic homogeneous distribution. coloured surfaces spatially characterized atomic force microscopy, images show presence defects on modified surface. formation micrometric sub-micrometric structures was observed related filamentation processes.
