Defects on surfaces of optical materials limit the performance of high energy and high peak power laser systems.
PLS scientists use the latest high sensitivity and high resolution optical characterization tools to understand laser-materials interactions.
Optical materials undergo laser-induced damage due to defects created by fracture and contamination.
Imaging these defects in 3D, and including photoluminescence lifetime information allows PLS scientists to understand mechanisms of defect creation and mitigation strategies.
High-resolution, high-sensitivity transmission loss imaging (down to 0.1%) is used to measure the effects of exposures to many low and high fluence laser pulses.
