Confocal and atomic force microscopies of color centers produced by ultrashort laser irradiation in LiF crystals

We report properties of the spatial and spectral distribution of color centers produced in LiF single crystals by ultrashort high intensity laser pulses (60 fs, 10 GW) using confocal spectral microscopy and atomic force microscopy. We could identify a large amount of F centers that gave rise to aggr...
