For this tutorial you can use any SpeedMarker series, Speedy fiber or Speedy flexx laser machine. Please note that MOPA laser sources are only available for SpeedMarker laser machine.

Important information:

Depending on the alloy, the laser marking results on your chosen stainless steel may differ from those shown in this tutorial.
To achieve different colours, the pulse width has to be changed. This means that you can only achieve black laser marking results using a standard fiber laser source.
