It looks like the discovery 10 years ago is finally making it into laser marking systems you can buy. Color Laser Marking Color palette is limited by the metallic oxides that can be produced but way cool.
Will this work with our CO2 lasers? The linked article only mentions fiber lasers.

Only fiber lasers as they adjust the pulse width and frequency to make different metallic oxides on the surface of the material.

How much is a fiber laser and how big are they?
This looks like a potential replacement for doing anodization.
I also see potential using that instead of silk-screening or decals for project enclosures.
They are using galvo scanning heads so the area is generally small 6x6" up to 12x12". Prices from $4k-$20k. MOPA Fiber lasers in the 30+watt range can do deep engraving. Fiber Lasers are very efficient devices and damn cool.

I believe Trotec makes a dual-source CO2/Fiber laser system.
