Abstract:
Substrate preparation before coating and coating cleanliness are the dominant factors affecting laser-induced damage to antireflection-coated LiNbO(3). Careful control of these factors resulted in an order of magnitude improvement in the damage threshold to 15-20 GW/cm(2) at 30 nsec across the entire surface.
