Title: Self-formation of quasiperiodic void structure in CaF{sub 2} induced by femtosecond laser irradiation

Abstract

We report the self-formation of quasiperiodic void structure with the length of several hundred micrometers inside the CaF{sub 2} crystal. The quasiperiodical voids along the propagation direction of the laser beam were formed spontaneously after the irradiation of a single femtosecond laser beam which was focused at a fixed point inside the crystal sample. The length of the void array varied with the focal depth beneath the sample surface. The possible mechanism of the self-formed void structure was discussed.
