This technique is called laser ablation and it uses CO2 or fiber lasers for it with very short pulses

Why isn’t it damaging the floor?

i am sure it can. The layer is taking a very small layer off. Lasers heat up what it hits. Since it's on concrete, the damage is zero in quick paths i assume.

Just a guess

If you look closely you can see that it's leaving marks on the floor
