Nonlinear optical analysis of bulk oxidized carbonaceous materials response

In this study the nonlinear optical response of porous μm sized carbonaceous particles (cp) was studied within the self-action of 42 ps laser pulses at 1064 nm. Photoinduced absorption efficiency (PAE) of air-thin layer of cp was examined versus the total surface area of cp. The porous thin layer sh...

Summary:In this study the nonlinear optical response of porous μm sized carbonaceous particles (cp) was studied within the self-action of 42 ps laser pulses at 1064 nm. Photoinduced absorption efficiency (PAE) of air-thin layer of cp was examined versus the total surface area of cp. The porous thin layer shows predictably discrete response, depending on the level of the surface oxidation. Surprisingly, the ratio between PAE and the surface area show a constant trend within the experimental error range. This observation makes NLO response a promising regulator could be used in metrology of related bulk porous materials.
