Resumen:
We demonstrate the formation of laser-induced periodic surface
structures (LIPSS) in bismuth (Bi) thin films by irradiation with
nanosecond laser pulses. We report on the formation and the destruction
of the LIPSS as a result of the delivered number of pulses; both the
formation and destruction threshold were very well determined. Results
show that the obtained LIPSS are perpendicular to the laser
polarization, and their ripple periodicity is on the order of the
irradiation wavelength. Although all the irradiation experiments were
done in ambient air, Raman micro-spectroscopy indicates that the LIPSS
are constituted by metallic bismuth, i.e. the LIPSS formation is
oxidation free. (C) 2017 Optical Society of America
