Abstract: An apparatus for coating a surface of a substrate includes an evaporant source disposed within an open environment including air at atmospheric pressure. The evaporant source includes a coating material. The apparatus further includes an energy beam source disposed within the open environment and configured to emit at least one energy beam that impinges on an emission region of the evaporant source to form a vapour plume at the emission region. The vapour plume includes the coating material of the evaporant source. The apparatus further includes a fixture configured to position the evaporant source relative to the substrate within the open environment, such that a maximum distance between the emission region of the evaporant source and the surface of the substrate is less than or equal to 10 cm.
