20W/40W Laser modules: new PCB engraving method?

I’ve seen one video where it seems that the 2W IR laser (upcoming) may be able to do this. A 30 W 1064 nm Laser certainly can: https://www.youtube.com/watch?app=desktop&v=d7yR-QOJuos

With 2W IR lasers out in the wild, I wonder why you find only very little info on the topic of circuit board with 2W IR…
