| Popis: | Optical limiting (OL) is observed for detonation nanodiamond clusters (ND) suspended in water with mass concentrations of 3-0.01%. By using nanosecond Z-scan measurements at 1064 nm we demonstrate that the nonlinear light scattering strongly contributes to the OL in a wide range of ND concentrations. Moreover we show that the ratio of the nonlinear and linear extinction that can be seen as figure of merit for an optical limiter is a non-monotonous function of the ND concentration. Our analysis reveals that the concentration that corresponds to the optimum OL performance essentially depends on the incident intensity. In this paper we report the OL performance of aqueous ND sus- pensions as a function of the ND concentration. The obtained results show that these suspensions can be employed in the optical limiters with different initial transmittance coefficients. We also find out the optimum concentration of nanodiamond particles that gives the maximum reduction of the transmittance coefficient. |
