Laser engraving slate Answered

Hi all
Thinking about putting a project together based on some of the great instructables on here.

Can anyone shed any light on how much power I will need for a laser that will engrave slate? I am not sure whether a diode laser will be up to the job or whether it will have to b a co2 laser.

Any info would be appreciated.

Look for a 40W Laser. Best option would probably be a CO2 laser.
