Let us here stress the existence of the bandshift induced by laser as given by Everall, et al., 1991. In the Figure of their work, we can find depicted the "laser-induced bandshift in single (40 μm diameter) graphite grains: (a) E2g mode, 1 mW laser beam power at sample. (b) E2g mode, 6 mW laser beam power. The original band position was restored on returning the laser power to 1 mW". Everall and coworkers told that "the likely explanation for these effects is that localised sample heating occurs and distorts the vibrational spectrum, although a simple interpretation in terms of expansion of the graphite lattice parallel to the layers cannot hold, since the in-plane coefficient of thermal expansion is negative below 400 °C." In the following figure, on the left, it is given the analysis of obtained with 1 mW beam power, on the right that for the 6 mW case. The peak is fitted by a q-Gaussian (see pag.50 of article available SSRN). by On the left, the peak is given at 1575 cm -1 , the beam power was of 1mW; on the right (1565 cm -1 ) the power was of 6 mW. The q-parameters of the best fit are different. On the left, q=1.78, on the right q=1.48 .
