How's this for a nonconstructive activity? I went to the trouble of combining red, green, and blue beams. Then I took them apart again. But it sure is sexy. OH yes.

Start with your typical (or not so typical) white beam:



And add smoke and various diffraction gratings













Total output was around 300mW

I only spent 20 minutes or so this time around, so you may be able to see misalignments or skewed ratios.

My hosting service has been having a lot of troubles lately. They're still there, but the server goes down fairly often, sometimes for hours at a time.

They load as of this post, anyway.

Yes, that's my 50mW single line argon. I didn't measure the outputs this time, but they should still be at a ratio close to 4:1:2 totalling around 300mW.



The rightmost optic in this lot from ebay can be used as either a red/green, green/blue, or red/blue depending on the angle of the incident beam. I used it to combine the green and blue. For the sea-green/red dichro, I used a strange unidentified pane of glass I found in a dead digital camera.
