I have a goal to create a laser that I can swap between different wavelengths, but will still line up more or less.
I was hoping to see the difference in peaks distances when passed through a dual slit with different wavelengths. So like and RGB laser in many ways, but I am not trying to mix them. The easiest way to do it seemed to be dichroic mirrors, but I am having trouble finding nice square ones that will be easier to align except on ebay from eastern europe. I was hoping someone would sell them more locally at a reasonable price, or that someone might have a better idea about accomplishing what I wanted. Originally I was going to try and mill an aluminum disc with holes for laser modules that I could rotate to line up, but the power hookup seemed like it would be quite a hassle since they were spinning, unless I mounted batteries on the back of the disc, but that would also be a hassle to get them to select the correct module to turn on. Then I realized with RGB alone and 3 lasers I could just run the dichroic mirror and relays to turn individual laser on and off. That seemed easier. Any other suggestions would be welcomed as well as suggestions for where to pick some dichroic square mirrors in the US.
