Paper Abstract

The passive optical limiters are of significant for protecting sensors and human eyes from high intensity laser. The selection of materials is still one of the key for optical power limiters. The nonlinear optical properties of pentaazadentate metal complexes (PMC) were measured, the third-order optical nonlinear polarizabilities of 1.19~3.38x10-13esu were obtained, from which the molecular second order hyperpolarizabilities of 8.0x10-32~2.83x10-31esu were calculated. The optical limiting performances for PMC have been studied at 532nm for 8ns and 35ps pulses by using nonlinear absorption technique, in which the reverse saturable absorptions in the T1 and S1 states were responsible for the optical limitings. Experimental results demonstrated that the peripheral substituents and center metal ions influenced the third-order optical nonlinearities and the optical limiting performances of PMC.
