Would a laser that's the thickness of an atom cut through us or is it too small and just pass through?

A laser that's the thickness of an atom would have to be an x-ray, because the size of a light wave is dependent on its energy. X-rays do not interact with materials very strongly due to their high frequency.

If you had enough energy to actually interact with a material, it would just melt the material. Generally speaking thermal conduction is quite fast and you'd end up melting a large area around the spot.

You are thinking about lasers in terms of physical objects. Lasers are light, and light exhibits many more wavelike properties than particle properties. A photon is just a quantization of light energy.
