The fiberglass I was trying it on was either FR-4 or G-10 circuit board fiberglass. Circuit board fiberglass typically uses epoxy resins, so may give very different results from what the pool cue uses.
What I'm also remembering now about doing it was watching the resin turn liquid long before the cloth was effected, and the cloth scorching much wider than the beam, long before the beam made a dent in it.
That may just be because I was doing it to a circuit board fiberglass, but I suspect no matter what the resin, the power needed to effect the glass cloth is far higher than needed to melt the resin.

It's good to hear it came out right. I'm engraving 500+ pieces of kitchen utensils right now and most of them are covered with graphite, like this setup you've just described, it looked like it could go really wrong, but ended up engraved very nice in less than 3 minutes, setup not included.
Keep on experimenting, learning never stops with lasers.
