##   *Salmaan Baxamusa*  |  17-ERD-003 

###  Executive Summary 

 We are exploring why laser illumination initiates surface damage in nonlinear crystals, and we are developing processing technologies to fabricate crystals with superior resistance to surface damage. Enhanced damage resistance will enable more efficient operations at the National Ignition Facility, as well as enhance designs for new laser systems for wide-ranging applications in defense, scientific research, and manufacturing.
