Yes*.

> are they cutting through things

No, they heat things until they explosively boil off.

* Depends on total light intensity and photon energy. X-rays are not great for you. Being 30cm in front of a stadium floodlight is not great for you (and your clothes unless you are wearing fireproof duds). Feel free to bask in the light of your kitchen lightbulb.
