    Under certain pulsing regimes, acoustic resonances are set up in the laser which perturb the beam pointing characteristics. To ensure stable beam pointing, avoid operating the laser within the grey shaded areas in the graphs.

    Appendix F. Applications troubleshooting This appendix addresses common materials processing issues, their causes and corrective actions. F.1. Common issues Fluctuations in beam intensity at the workpiece The intensity changes can cause variations in marking intensity on some materials. Focus spot height changing relative to the workpiece When beam delivery optics heat up and distort, the focus spot height can change relative to the workpiece.
