title: Polarization dependent ripples induced by femtosecond laser on dense flint (ZF6) glass.
abstract: We report on the formation of polarization dependent ripples on ZF(6) glass by femtosecond laser irradiation. Two kinds of polarization dependent ripples are formed on the laser modified region. The ripples with direction parallel to laser polarization distribute in a pit in the center of laser modified region, the period of the ripples increases with the increasing pulse number. The ripples with direction perpendicular to laser polarization spread around the pit, the period of the ripples (~750 nm) almost keeps constant with the increasing pulse number.
