I have a question that I haven't found any information elsewhere on how to approach. Just because yahoo answers seemed particularly keen to sniff out homework and mock those asking questions by it, just to clarify this is for my own knowledge not for any project for school or anything. Anyway, I found that apart from objects light can't seem to disrupt itself and so what I want to try and find is a way to take a single photon beam and disrupt it with another beam. I thought since I haven't had the oppurtunity to find the necessary equipment to create a single photon beam that this may work in the meantime by everyones optics experience. So just to clarify my question simply is can a laser disrupt another laser, if so what would be needed, and if not why? Can if not the same frequency and laser a different frequency laser or intensity or something be a factor in the quality of a disruption. I don't think I asked this very well, but thank you in advance for the attention, no matter how small it may have been.
