Abstract: Laser ablation processing method for debris-free and efficient removal of materials comprises the step of using a refrigeration device to condense the water vapor and form a thin frost layer on the materials at temperatures below the freezing point. The residual debris produced during the ablation process deposits on the frost layer that covers the material, which is easily removed when the frost layer melts. At the same time, the frost layer in the laser irradiation area melts to a liquid layer, which can effectively reduce the deposition of debris on the inner wall of the groove and thus improve the efficiency and quality of laser ablation. The method is applicable to debris-free laser processing on an arbitrary curved surface.

Abstract: A method of fiber laser processing of thin film deposited on a substrate includes providing a laser beam from at least one fiber laser which is guided through a beam-shaping unit onto the thin film. The beam-shaping optics is configured to shape the laser beam into a line beam which irradiates a first irradiated thin film area Ab on a surface of the thin film, with the irradiated thin film area Ab being a fraction of the thin film area Af. By continuously displacing the beam shaping optics and the film relative to one another in a first direction at a distance dy between sequential irradiations, a sequence of uniform irradiated thin film areas Ab are formed on the film surface defining thus a first elongated column. Thereafter the beam shaped optics and film are displaced relative to one another at a distance dx in a second direction transverse to the first direction with the distance dx being smaller than a length of the irradiated film area Ab.
