I am having a hard time in finding out what exact light media laser shows use. I am trying to build a laser show myself. I know that the laser light is reflected off these particles in such a way that that it makes the laser line "viewable" in all directions
Can somebody explain to me how exactly do the collection of particles make it viewable in all directions and what exact conditions are necessary? Does the angle of the incoming laser light matter? Does the size of the particles matter? Does the uniformity of how the particles are dispersed matter? Would water vapor work?
I have tried using a fog machine, but the red laser that I am using only reflects off of the fog particles in a way that makes it viewable only from a certain perspective. This would not be a good show to the people standing in one side of the room vs. another.
