title = "Laser induced periodic surface structure formation in germanium above laser damage fluence by mid IR femtosecond laser irradiation",
abstract = "Laser induced periodic surface structures (LIPSS) were generated via interaction of multiple 90 femtosecond 1900-3600 nm mid IR laser pulses (3-10, 000) on single crystal Ge targets. For specific laser parameters, both low and high frequency LIPSS are found together, which are oriented perpendicular to each other. Study of polarization dependence of LIPSS revealed that orientation and symmetry of interaction could be controlled by rotating polarization of laser pulses. Low frequency LIPSS formation was consistent with surface plasmon coupling of laser pulses with excited Ge.",
