Abstract
We have developed an innovative lensless optical power limiting system for green region exploiting photoanisotropy of mesoporous films for low power continuous wave and high power nanosecond pulsed lasers. In Phase I, nanosecond response time has been obtained by the MesoPAD system we proposed. It is a promising technique for the next generation of laser eye and sensor protection. In phase II, mesoporous films will be optimized to reduce the exciting beam power requirement, improve the response time for ultrashort pulse application and explore avenues for broadband response. Protection at both low and high power over the entire visible region will be achieved, demonstrating Technology Readiness Level 6.
