From: Plastic deformation as nature of femtosecond laser writing in YAG crystal
(a) Scheme of DLW with the writing direction relative to crystallographic axes along with elementary crystallographic cell shown inside the sample. (b) Representative side phase images (under view along [110]) of tracks inscribed at different regimes of plastic deformation. The direction of the tracks is along [111] crystallographic axis; the direction of the laser beam is along [211]. The plane of the figure is a (110) crystallographic plane. The writing direction is from right to left. Ein = 70 nJ. Scale bar is 10 μm.
