Abstract: Methods are provided for etching, cutting and/or altering, the surface of a flower, plant, cut foliage, or foliage incorporated into consumable products such as cigars (hereinafter referred to as foliage, leaf, or product) with computer controlled laser energy to affect a desired artistic or utility design or marking on the foliage. The laser energy source is operative to provide an optical beam having power and optical wave length characteristics effective to thermally disrupt plant tissue to produce a permanent mark on the foliage surface or, alternatively, cut through the foliage. Additionally, methods are provided for the automatic transfer of leaves stacked in a container into the laser marking/cutting field and for depositing said leaves in a separate container after processing by laser. A method is described that provides for rapid, safe, and accurate manual placement of a leaf into a laser marking/cutting system.
