Abstract

We report the production of color centers in LiF single crystals by ultrashort high intensity laser pulses (60fs, 10 GW). An intensity threshold for color centers creation of 2 TW/cm2 was determined, which is slightly smaller than the continuum generation threshold. We could identify a large amount of F centers that gave rise to aggregates such as F2, F2+ and F3+. The proposed mechanism of formation is based on multiphoton excitation that also produce short lived F2+ centers. It is also shown that it is possible to write tracks in the LiF crystals with dimensional control.
