This part has been discussed at length actually. Beams will always be sensed by the light-adapted vision, because they are an intensely bright light source.

Sorry, I didn't now it. I think it's correct when talking about dots, not beams. Anyway, as said, this has been discussed at length, so no need to bring it back.

Beams should be the same too. Remember, a beam is an intense light source, and your photopic vision doesn't "switch off" since the surrounding environment is dark. The type of vision that is engaged depends on the type of light you're viewing. Laser beams are bright - usually ;)

I personally have a 100mw 405nm laser and a 50mw and I can NOT see the beam at all. These lasers are LPM'd and still burn really nice. Most, if not all of my friends say they can see the beam, but I can hardly see the dot. It really is different from person to person and I have 20/20 vision. Even when I smoke a room up, I can just hardly see the beam while I can easily see the beam on a 1mw red laser, however, I blame my eyes.

Let your eyes become dark adapted. That will take as much as 30-45 minutes even longer to become fully adapted. In your case visual acuity is secondary.
