    Is there a way to get light to perfectly interfere with itself that is easier than using a Michelson interferometer? I came up with a device called LIGO in my research, and it seems awfully difficult to accomplish the perfect alignment that they want. They are probably using the best method available to them, considering top optical engineers designed it, but perhaps there is a way to get perfectly aligned diffraction outside of their requirements? I know that they need it to vary between perfect diffraction and less amounts (hence indicating gravitational waves), but what if your only goal is to constantly get perfect diffraction no matter what the conditions? Is there an easier way to do this than the hyper precise interferometer they use? I was thinking that maybe they could use such a constant interference device for variations on LIGO experiments that could be done on a smaller more economical level.

    I know this would result in interference 100% of the time if it worked, but will lasers of a different wavelength (say green and red) interfere with each other? I think the waves constantly going out of alignment with themselves would result in perfect phase cancellation at various points. If it worked, maybe there is a way to still make it sensitive to gravitational waves? or is that not possible?
