We study the behavior of optical materials at high laser intensities.
In Layman's Terms: We zap materials with high intensity lasers to develop new types of "nonlinear optical" materials
Applications: Protecting our troops and their automated systems from laser damage, high speed communications, advanced laser radar, fiber-optic switching networks, photonic phase array antennas, optical sensors, optical computers
Recent Achievements: We have developed the first materials that can be used for power limiting in the blue region, phosphine-substituted oligothiophenes
Experimental Example: Below is shown a "Z-Scan Experiment" to characterize nonlinear optical materials
