When I was a postdoc at berkeley I was talking to the head of the bioengineering department who mentioned the phenomena. He had actually written a paper in which he put an appropriate set of filters in front of a particle accelerator to ensure that a statistical photon was emitted at a specific frequency (IE, it output 1 photon/sec, although only on average). Then he sat in front of the filters at looked into the accelerator.

Still one of the most audacious things I've seen, but he was a good physicist and did the math right, so he wasn't being unsafe.
