Claim 8:
9. The apparatus of claim 6, wherein the perturbation assembly comprises a general purpose microprocessor or an application specific integrated circuit and the apparatus further comprises:
a memory storing a calibration table in which the two or more different beam characteristics are correlated with two or more different fiber perturbation values, respectively,
wherein the perturbation assembly is further configured to:
receive information about a demanded laser attribute for the tuning the delivery of the laser beam to the workpiece; and
perform a look-up from the calibration table based on the information about the demanded laser attribute, wherein the beam perturbation device drive level is identified based on the looked-up from the calibration table.
