title: Gradient-index AR film deposited by the sol-gel process.
abstract: Gradient-index alkali borosilicate antireflection films for use in laser systems were deposited by the sol-gel process. Laser damage thresholds of these films, measured with 1.06-microm 1-nsec pulses, were four times greater than thresholds of widely used, multilayer, antireflection coatings.
