摘要：
Three-dimensional extended arrays of micro-columns are generated on the surface of Ta and several stainless steels by their ablation by radiation of a Cu vapor laser either in vacuum or in air. The reflectivity of the arrays is tested in both visible and near-IR regions using the facilities at NASA Johnson Space Center. The reflectivity of the laser-treated areas was found to be very low (0.03-0.08) in the range 250-2800 nm. The emissivity of 3D arrays measured at elevated temperatures is close to the emissivity of a calibrated black body emitter. The effects of the experimental conditions of ablation (laser fluence, environment, etc.) on the integral optical characteristics of the generated arrays are discussed.
