Microengraving of a potassium dihydrogen phosphate crystal by laser ablation technique

We present proof-of-principle results regarding the possibility of micro-engraving Potassium Dihydrogen Phosphate (KDP) crystals using laser ablation techniques. The results of the work show that this technique can be used for realizing integrated optics and micro-optics components that are based on such crystals, one of the envisaged directions being that of integrated electro-optical modulators.
