INVESTIGATION OF PHYSICAL PROPERTIES OF carbon DIAMOND-LIKE COATINGS APPLIED BY PULSED LASER DEPOSITION

Abstract

Aim: determination of the thickness and optical constants of carbon diamond-like coatings applied by pulsed laser deposition to develop recommendations for technological modes of applying these coatings to copper and aluminum mirrors. Methodology. The infrared spectroscopic ellipsometry method is used to determine the thickness and optical constants of carbon diamond-like coatings. Results. The thicknesses and optical constants of carbon diamond-like coatings applied to samples of copper and aluminum mirrors by pulsed laser deposition were determined. Research implications. The optimal technological modes for applying diamond-like coatings by pulsed laser deposition to copper and aluminum substrates are determined from the point of view of optical characteristics.
