Abstract

The paper describes optical limiting properties of Si polymer with α

-π electron conjugate tracks. The transmissivity and light intensity of the sample in different concentrations at 532nm had been measured. The results show that the polymer is characterized by good optical limiting properties. Finally

an effective two photon coefficient β=3.5×10

-9

cm/W measured by Z-scanning method is given.
