Hello all.
So I want to start a new project, a RGB laser, in a lab style host.
I'm going to be using Dichros, and 50mw Green, a 40mw 445nm blue, and a 180mw red.
Now, I see 2 major problems;
One, is the different beam diameters. I'v never had a 445nm before, so I cant say how big it is, but a green will definitely be the thinnest, and the red will be quite big, this will create beams that have a messed up outer edge, so say for example I make a yellow, the green will be tiny and the red will create a red outer layer, instead of all yellow. How can I fix this? I had the idea of putting there red laser through a hole, so only a small portion of the laser gets through, but this will (apperantly) give me horrible divergence, so I dunno.
And second, the power supply to the 3 laser modules. Each laser will need different volts, the green about 3, the red about 5, and the blue, well, I dont know that one, so will I need to use seperate power supplies to power each laser?
If I only need one power supply for all 3 lasers, then when I switch just one laser on, will the extra power kill the lasers? so say the power supply puts out 18v and I switch on a green laser which needs 3v, will the cicuit compensate for the extra 15v, or will the green get all 18v?
I know these are noobish questions, but I just want to clarify before I drop money into this project, better safe than sorry :beer:
Thank you
P.S: Sorry if in wrong section.
