摘要

A meniscus coating method to produce multilayer laser reflectors on 30+ cm substrates is described. These high-laser damage threshold (LDT) dielectric coatings are deposited from colloidal suspensions of silica and alumina nanometer-scale particles. The deposition process involves forcing a slow suspension flow through a porous applicator tube, forming a falling film on the tube. A substrate contacts this film to form a meniscus, and then moves relative to the applicator to entrain a film upon itself, which thins to optical dimensions upon solvent evaporation. The fluid dynamics of meniscus coating are briefly described, and optically measured dried film thicknesses are compared to theoretical predictions. Deviations from the theory are traced to non-Newtonian rheology of one of the suspensions used. Preliminary multilayer coating results which focus on large-scale uniformity and LDT are presented.
