Micrometer-pitch surface and embedded gratings were inscripted in lithium niobate through multiphoton absorption excited via focussed femtosecond laser pulses. The drawbacks and the points of strength of the investigated line-by-line grating writing technique are discussed and compared to two beam interference. To the best of our knowledge, it is the first report of embedded gratings in Lithium Niobate.

Abstract
Micrometer-pitch surface and embedded gratings were inscripted in lithium niobate through multiphoton absorption excited via focussed femtosecond laser pulses. The drawbacks and the points of strength of the investigated line-by-line grating writing technique are discussed and compared to two beam interference. To the best of our knowledge, it is the first report of embedded gratings in Lithium Niobate.File in questo prodotto:
