Visible and Infrared Laser-Induced Damage to Transparent Materials.

摘要

The basic objectives of this program was to analyze data obtained from carefully controlled damage measurements at laser wavelengths between 0.69and 10.6micrometers and at various laser pulse durations. The effort was divided into six major areas:They were (1) design and assembly of a pulsed CO2TEA laser for use in 10.6micrometer damage measurements, (2) a study of the effects of lattice disorder, polycrystallinity,alloying,and atomic impurity doping on intrinsic damage fields, (3) measurements of the dependence of intrinsic breakdown fields on laser pulse duration, (4) bulk and thin film optical damage from inclusion absorption, (5) the relationship between self-focusing and optical damage,and (6) analytical studies of laser-induced electron avalanche breakdown.
