Determination of a dose-like curve for active colour centres produced in LiF single crystals by ultrashort high intensity laser pulses and a preliminary investigation of their spectral and spatial properties by confocal and atomic microscopies

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 of the centres were measured conventionally and also by confocal microscopy. A large amount of F centres that gave rise to...
