Knowledge:

Briefly reason analysis of uneven marking effect of fiber laser marking machine(1)

First, the use of partial focus to mark a certain range of content

Because each focusing mirror has a corresponding range of focal depth, using partial focus will easily lead to that when marking a large range of pattern, the edge is at the critical point of focal depth or beyond the range of focal depth. Therefor, it is easy to cause uneven effect. Therefore, laser energy must be taken into considered in the method of partial focus marking.

Two, the laser output spot is blocked, that is, the light spot formed by the laser beam going through the galvanometer and field mirror gets partly missing, not round enough.

If the laser output head, the fixing fixture and the galvanometer are not adjusted properly, it will lead to the blocking of some light spots when the laser passes through the galvanometer; and the light spots presented on the frequency doubling plate after focusing by the field mirror are non-circular, which may also lead to uneven effect.

There is also a case is that the dipole deflector lens is damaged. The laser beam is not reflected well as it passes through the damaged area of the lens. 

Therefore, the laser energy of the beam passing through the lens damaged area is not consistent with that of the lens undamaged area, and the laser energy acting on the material is also different, thus making the marking effect uneven.
