Nonlinear Optical Properties of Graphene and Carbon Nanotube Composites

Size effect on the optical limiting in suspensions of detonation nanodiamond clusters

“…It is clear from Figs. 4(a) and 4(b) that in all studied samples, the OL at 532 nm is accompanied by the nonlinear light scattering, which may be caused by the formation of microplasma in the focal area [5]. It is worth noting that in contrast to OL in carbon black [6] and CNT suspensions [8], we observed no vapor bubbles in our experiments.…”

“…The most important requirements for the optical limiters are a wide spectrum range and short response time [4]. That is why nanocarbon materials, which have a strong and broadband absorption in the visual and infrared spectrum range, are recently considered as most promising for the OL applications [5]. Among these materials are carbon black [6], graphite [7], carbon nanotubes (CNT) [8], onion-like carbon (OLC) [9], and nanodiamonds (NDs) [10], however in the last decade, the most attention has been attracted to aqueous suspensions of carbon black and CNT [6,8,[11][12][13][14][15][16][17][18][19][20].…”

Comparative studies of optical limiting in fullerene and shungite nanocarbon aqueous dispersions

“…Among materials for optical limiting applications dispersions of carbon nanoparticles are rated quite high and intensively studied to date [1][2][3][4][5][6][7]. Indeed, they are either colorless or slightly colored and have both a wide working spectral range (from visible to near infrared light) and a considerable limiting efficiency (10 2 -10 3 times).…”

Heat generation and conduction in PDMS-carbon nanoparticle membranes irradiated with optical fibers

“…Therefore, the light transmitted through the composite seems to decrease in a nonlinear fashion as the optical power increases. This behavior has been actually used in optical devices in order to impose a light transmission limit and guarantee power-dependant light screening [17].…”
