Paper Abstract

The considerably interest in the possibility of fabricating efficient optical limiters based on solid-state materials have led us to develop an easy method for producing RSA compound doped in PMMA. The chosen RSA dye was a soluble silicon phthalocyanine (SiPc(OC7H15)). By comparing the non linear absorption of this compound in solution in THF and in PMMA, we show that broadband solid-state limiters can be made with such a dye for visible nanosecond-pulse excitation. The importance of broadband criterion such as the photopic transmission to adjust the transmission at low incident energy in conjunction with the color neutrality are also stressed.
