Acousto-optical Process Control for Laser Ablation and Laser Welding
Authors: Contents:- The optical microphone has proven effective and invaluable as a measurement instrument during laser processes.
- The measurements obtained are useful in:
- the automated calibration of the optimum focus spot of a laser beam,
- controlling the laser ablation quality in a production line without modifying the workpiece, and
- identifying keyhole formation (or lack thereof) during laser welding processes.
