Abstract

The present application relates to a marking head for a laser marking system comprising a CO2 laser source (1) configured to generate electromagnetic radiation, and an electromagnetic radiation steering mechanism (2) configured to steer the electromagnetic radiation to address a specific location within a two-dimensional field of view. The electromagnetic radiation steering mechanism (2) comprises an electromagnetic radiation manipulator configured to introduce a difference between a first angle defined between first and second rotational axes and a second angle defined between first and second steering axes. The CO2 laser source (1) has a dimension in a first direction that is greater than a dimension of the CO2 laser source (1) in either orthogonal direction to the first direction. The marking head has a dimension in the first direction that is greater than a dimension of the marking head in either orthogonal direction to the first direction.
