Claim 16:
17. The apparatus of claim 11, wherein the perturbation assembly comprises a general purpose microprocessor or an application specific integrated circuit, wherein 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 variably controlling means is further configured to:
receive information about the demanded laser attribute for the delivery of the laser to the workpiece; and
look-up one of the fiber perturbation values from the calibration table based on the information about the demanded laser attribute, wherein the control signal is generated based on the looked-up one of the fiber perturbation values.
