Abstract

Ion and electron microscopy was used to characterize micro- and nanoscale surface and subsurface defects in LiNbO3 formed during femtosecond laser processing. In each case, the ablated region is surrounded by amorphized material as well as a region containing highly defective crystal. The subsurface structure is completely amorphous with a void at the top of the structure, and an amorphous channel which reaches through the surface as a result of the explosive nature of the material-laser interaction.
