Engraving titanium G2

Has anyone ever tried to engrave Titanium G2.
If so what are the settings

You can’t engrave titanium with a diode laser. Wrong wavelength and not powerful enough. Need a fiber laser for that.
You might be able to mark it using a marking spray like Cermark’s or the poor man’s version, dry moly spray lube. Or you can use the laser to remove coatings like paint or powder coat or anodizing,
