Nice first step -- how do you get color ??? I can make single spots with my little nDYAG but the lens doesn't like it. Nice view of the future................

OH -- I see that I'm an "Unknown Quantity" at this point !!!! I know my limits when I go for a drink !!!

The plasma looks kind of purple, but perhaps that's just the way the camera sees it, like the beam of near-IR lasers....not sure what color it would be to the eye.

When air is turned to plasma, it looks blueish white from my NdYAG. Like lightning.
