Laser system for producing a laser marking on a surface

The laser system (1) has a radiation source (11), which emits a laser beam (14) along an optical axis (16), where a deflection is provided with a deflection optic (19), which deflects the laser beam as deflected laser beam (21) along another optical axis (22). The delfection unit is adjustable in accordance to the laser unit in such a way that the radiation source is arranged in a housing (10) and the deflection optic is arranged in another housing (18).
