Not as much as you might think. Fog puts water particles into the air while humidity is water molecules which don't cause visible light to be refracted off of them to anywhere near the degree of water droplets. If it doesn't refract ordinary light, it won't refract laser light either. If the humidity condenses into fog, then you will have what you need to show a laser's beam brightly.
Understand your point. I have read that a laser beam would not be visible in outer space since there are no molecules in outer space; yet the beams are visible in the Earth's atmosphere so there must be some refraction. Do you know of any examples of comparing laser beam visibility at sea level compared to at the top of a mountain.
On another topic I am wondering about pointing a laser into what I will call low level clouds or what I call 'pea soup dew'. Keep in mind that I spend a lot of time in places that would not always qualify for a third world country. I have also been on beaches where spindrift produces obvious moisture on my body/clothes yet there are no visible 'water droplets' in the air.
Not sure if this is making any sense and I really only have used very low end lasers so I hope this is not a really silly question.
