I suspect you can’t find info about it because it’s not a good candidate for the GF–the voids and aggregates that form concrete will likely leave very uneven results (even if no other risk), and rather wastes the accuracy and fineness that the laser is really appreciated for.
Even very fine concrete contains various sizes and types of stones and components and takes a lot of work to remove all the air–stepping stones usually are on the coarser side of the materials used and little attempt to remove air from the mix…
