Abstract

A laser marking apparatus has a number of individual laser devices (1) mounted at angles to one another. The output ends (2) of the laser devices are disposed closely adjacent to one another and a number of laser beam redirectors (5) are disposed to intercept the laser beams (3) emitted from the laser output ends (2) so as to extend the length of the laser beam paths and to decrease the angle between said laser beams (3).
