(a,b) AFM height image of GO surface after focused laser irradiation at different spots for various laser power. Bending due to 0.026 mW and 0.085 mW laser are highlighted with dark blue circles in Fig. 3a. Scale for both (a) and (b) are same. (c–f) High magnification 3D view of the AFM images showing bending of surface due to the laser power of 0.26 mW, 0.78 mW, 0.96 mW and 1.48 mW. (g) AFM image in 3D representation of the void formed while the laser power reaches breaking point at 1.59 mW, where the etching gets ignited. (h) Variation of bending depth and bending diameter as a function of laser power.
