Study of polymer optical limiting materials

With the fast development of modern laser technology and laser arms, there has been a growing need for optical limiting materials and devices to protect optically sensitive devices and human eyes from laser damage. Particularly, optical limiting polymer materials have also attracted great interest due to their distinguishing features, such as their large third-order nonlinearities, faster nonlinear response times, high damage thresholds, ease of processing and structural modification, and their applicability over a wide range of wavelengths. In this paper, recent advance of optical limiting polymer materials was reviewed in detail with an emphasis on molecular structure of polymer materials and optical limiting mechanism, and effect of molecular structure on optical properties of optical limiting polymer materials. The future development prospect of optical limiting polymer materials was proposed.
