Apparently it's doable with that range. Power's going to determine how much you can cut through and the speed at which you can engrave.

Also, someone has to say it: if you're going to be dealing with lasers make sure you get wavelength-appropriate safety glasses and an enclosure. If you're going to be keeping an eye on it cardboard should work to keep reflections at bay. Even at the 200mW range, you can do a number on your eyes.
