A method and a control device for deflection of a laser beam for laser-based additive manufacturing processes includes first and second orthogonally rotatable mirrors designed to reflect the laser beam and guide the laser beam to an irradiation field. The first mirror and the second mirror are secured on respective first and second shafts, with the first mirror performing a continuous first vibration with a first frequency, and the second mirror performing a continuous second vibration with a second frequency different from the first frequency and/or with a phase difference with respect to the first vibration. Each of the two shafts has a known position such that the first vibration is synchronous with the second vibration. The laser is activated/deactivated upon reaching/leaving an irradiation point. The generated vibrations of the mirrors describe a continuous Lissajous curve.
