Hi Rainbow, the red is a Skylaser 650nm 200mw. On the second photo you reposted, a flashlight was used, so it probably lightened up the red a little. Also a fog machine was used that could also lighten up the beam since they are time exposures of a least a few seconds.
I was thinking, hopes its not very confusing but.. What happens when you shine two different colored lasers at the same spot at different angles in order to combine the colors on the other side to make a new color? Might look cool
I actually tried that with a red and green and got some yellow in the middle of both beams. I am not sure if it is from physics of the different interaction of the beams or something with the camera. I will post some pics for you in afew when I get on my computer
