What happens if the air is saturated? Does the molecule clump just settle back down where it came from, or would it stay suspended somehow in the air (mist?)?

Alternatively, I wonder if this could be used as a super swamp cooler, I'm picture water dripping or flowing from a tube, a laser causing it to "burst apart", and then the droplets formed rapidly cooling the surroundings due to their surface area.

It seems possible we could improve swamp cooling with this, as with desalination, though in general you want to avoid putting energy into the system, I think. Powering a laser might overcome the benefits... unless you shot lasers in from outside? Even so, it might be best to use [filtered?] natural light for such a system.
