From: Reversible writing of high-density dislocations with multidimensional controllability in PMN-PT crystal

Fig. 4

a Dependence of the length of a dislocation-formed zone on pulse number and pulse energy. Pulse duration is set to 885 fs. Inset: the top view of dislocation-formed zone. b Dependence of the length of a dislocation-formed zone on pulse energy and pulse duration. The pulse number is set to 150k. c Process windows for laser-writing dislocations. Pulse number is set to 150k. d Process windows for erasing dislocations. Dislocations are first written using optimal laser parameters in Window II, and then erased with laser parameters in Window A, B, and C. e 3D process windows with respect to pulse energy, pulse duration, and pulse number for dislocation writing and erasing in the PMN-PT crystal. More detailed 2D process windows see Supplementary Fig. 14. f Experimental results of multi-cycle dislocation erasing and rewriting. Red dots and blue dots correspond to the lengths of the dislocation-formed zone after writing and erasing, respectively. Source data are provided as a Source Data file.
