The physical mechanisms of energy deposition by high average power lasers in optical materials and subsequent material response. The development of non-destructive diagnostic methods to identify laser-induced damage precursors in optical materials and monitor the effectiveness of damage prevention, repair, and containment strategies. The use of optical spectroscopy for noninvasive in vivo identification, characterization, and monitoring of the treatment of pathological or injured tissue.
