Resumen:
We report on the in-depth micro-modifications induced by
femtosecond laser ablation in Nd:YAG crystals. Near Field Optical
experiments have revealed that, below the ablated volume, a permanent
change in the Nd:YAG reflectivity, extending parallel to the irradiation
direction, has been induced. Micro-luminescence experiments have
provided experimental evidence that these permanent changes in the surface
reflectivity are accompanied by strong changes in the luminescence
properties of Nd3+ ions revealing relevant micro structural modifications in
the Nd:YAG system.
