how to mark color using Q-switched laser marking machine-ivy

Maybe many people have some confusion of how to mark color using Q-switched laser marking machine.

This letter is about the comparison of Mopa and fiber:

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.
