Κατεργασία διάφανων υλικών με υπέρβραχυς παλμούς λέϊζερ

Periodic structures in nano and micro scale were observed on transparent material surface after irradiating with femtosecond laser pulses. The periodicity of those structures can be manipulated by the fluence, the number of pulses and the wavelength of the incident beam. Also the orientation and morphological shape can be manipulated using a variety of polarizations such as linear, elliptical, circular, radial and azimuthal polarization. Taking advantage of that, complex structures can be produced aiming to create biomimetic surfaces which have similar properties with the subject
