Abstract
The present invention relates to a method for smoothing and polishing surfaces by treating them with energetic radiation, in particular laser radiation, in which the to-be-smoothed surface is remelted in a first treatment step using said energetic radiation and employing first treatment parameters at least once down to a first remelting depth of approx. 5 to 100 μm, which is greater than a structural depth of the to-be-smoothed structures of said to-be-smoothed surface, wherein continuous radiation or pulsed radiation with a pulse duration of ≧100 μs is employed. The method makes it possible to automatically polish any three-dimensional surface fast and cost effective.
