The difference of many kind laser marker machines-Tulsa
In order to make clients know more and choose suit fiber laser marker machines, we offer any suggestions.
No.1 Mopa and fiber laser difference of laser marker machines
MOPA laser and Raycus or IPG laser are both 1064nm wavelength laser beam, so this deciding what kind of material it can engrave.
But there is still difference:
MOPA laser source is Pulse width (2ns-250ns) and Pulse frequency (1-1000HZ) , so MOPA laser is more flexible.
Raycus or IPG laser is Normal Q-Switched laser source, Pulse width and pulse frequency are fixed, can not be changed.
Pulse width 90-130 ns , repetition frequency 30-100 kHz
MOPA laser also can mark black color on anodized aluminium
here is video:
For Marking different color on stainless steel, Normal Q-Switched laser source can also mark color on SS, here is video
MOPA fiber laser machine can mark different color on stainless steel more easily than Normal Q-Switched laser source.
No.2 The marking depth method
About engraving depth, it need multiple layers for marking.
That means there are two layers, one layer parameter is Higher laser power, slower speed, for engraving depth.
Another layer parameter is Lower laser power, faster speed.
This layer is for removing the dust, so you can see it is white color in the photo.
