Investigation of microdamage to dielectric coatings by laser radiation
M. B. Svechnikov, L. S. Vakhmyanina
Abstract:
An experimental investigation was made of the behavior of microdefects in refractory oxide and sulfide-fluoride dielectric coatings in the prethreshold range of exposure to laser radiation. The results obtained demonstrated clearly that the centers of optical breakdown in ZnS and SrF2 (or MgF2) coatings were strongly absorbing microinhomogeneities, whereas in coatings made of ZrO2 and SiO2 neither the concentration of microinhomogeneities (of > 1 μ size) nor their dimensions were affected by the action of a pulse (or a series of pulses) of power density just below the threshold.
