Fiber laser marking machine is widely applied to metals engraving,nowadays many customers have one question:how to do color engraving on metal with fiber laser marking machine? Today we will show you our color engraving on stainless steel with mopa fiber laser color engraving machine.

M&ZLASER has focused on laser marking machine industry for more than 16 years, we have rich experience of all kinds of laser marking tech. We will guide you how to mark different colors on stainless steel with a mopa fiber laser color engraving machine.

Another fiber laser is called Mopa fiber laser marking machine, this type machine is nearly all same as common fiber laser, but its price is much higher than common type. because its laser source is mopa structure, its working efficency adjusting range is much wider:1-4000Khz. While common type only 20-60Khz. What's the biggest difference is that Mopa type laser source can adjust laser pulse width:1-500ns. While common type laser source, can't adust, it is fixed pulse width.

Because of diffraction effects, oxide films of different thicknesses can be presented in different colors.

Step 3, In the presence of a mixed state of colored oxide and oxide film.
