RGB white laser for holography?
Posted: Thu Nov 04, 2021 12:43 pm
I want to make reflection holograms from long distances away (10ft?) in rgb color. I need a powerful RGB laser.

I want to get the "1w" version of this. I want to use a microscope objective as my diverging lens, I am not sure what would be the best option. I know you can change the multiplication and make the hologram come out more or less life sized but I dont know much about that. I need to read into it more.
It has a red laser 180mw, green 180mw and blue 650mw. I dont know why the blue is that powerful. I dont know if the laser is a TEM00, its probably not. I dont know if it matters that much. I think the temp regulation is already built in.
I am going to use Lippmann plate recipe for the exposure. They are more or less the same thing as holographic plates (just thinner, slower?) and I wanted to try Lippmann too. I figure maybe the thinner emulsion will work better to let more light through to the object? I dont know
