Optical limiting in nanodimensional products of laser pyrolysis of a dielectric liquid

The action of high-power neodymium laser pulses on organic dielectric liquids in the presence of a catalyst (ferrocene) leads to the formation of quasi-spherical nanodimensional carbon particles with a specific complicated structure. The obtained solutions exhibit the phenomenon of optical limiting for nanosecond pulses of the first and second harmonics of a neodymium laser.
