Figure 4: Plots of bending depth and diameter vs. laser power.
From: Graphene Oxide Demonstrates Experimental Confirmation of Abraham Pressure on Solid Surface

Graph shows the changes in (a) depth and (b) diameter of the laser irradiated spots as a function of laser power. Dotted line indicates the fitted plot of depth and diameter with variable laser power. Both depth and diameter shows linear dependence with laser power whereas this linearity breaks at 1.59 mW laser power, which is the breaking point.
