Аннотация: The results of experimental studies of optical power limiting (OPL) and nonlinear light scattering (NLS) at a wavelength of 532 nm in suspensions of detonation-synthesis modified nanodiamonds (MNDs) with different grain-size compositions are described. It is found that, at the same nanoparticle concentration, OPL and NLS are more efficient in suspensions with large MNDs. It is shown that MND suspensions can exhibit a stable long-term operation as OPL in a field of laser pulses with a power density of 0.2 GW/cm(2) at a repetition frequency of 1 Hz.

Аннотация: The nonlinear scattering of light under the conditions of optical limiting of nanosecond pulsed laser radiation at a wavelength of 1064 nm in a nanodiamond (ND) hydrosol has been experimentally studied. Superstable hydrosols were obtained from detonation NDs with a modified surface. Using an improved scheme of z scanning, it is shown that a decrease in the optical transmission coefficient of an ND hydrosol under optical limiting conditions is due to enhanced nonlinear scattering. It is established that the energy of pulsed radiation scattered at a right angle obeys a power law in dependence on the energy density of incident radiation pulses. Hydrosols of detonation NDs with the modified surface exhibit high stability with respect to the periodic laser action at high power density.

Аннотация: We report on the polarization dependence of the optical limiting and nonlinear light scattering in nanodiamond clusters suspended in distilled water. The nanosecond Z-scan measurements at a wavelength of 532 nm reveal that the nonlinear transmittance of the suspension is independent of polarization, while the energy of the light pulses scattered at 90 deg shows a cosine-like dependence on the polarization azimuth of the incident beam. Moreover, the ratio of the energies of the vertically and horizontally polarized scattered pulses is a nonmonotonous function of the input fluence. The obtained results can be explained in terms of the change of scattering center size under the laser action and are in agreement with the predictions of the Rayleigh-Mie scattering theory.
