What exactly you mean by this?

Do you intend to carve a groove in the wood but withou burning it with a laser machine?

carve a groove with the laser

To carve a groove with laser you will always burn wood.
What you can do is remove burned area with sandpaper.
Depending on your needs maybe a milling machine or a hand router suits you better for that kind of job.

Are you attempting to not burn all the way through? Different pieces of wood (even wood from the same tree) can offer a great deal of variability.

Is the groove for Joinery?
