Something like this I suspect, though I'll have to wait for the physics heavyweights to weigh in.

I'd guess a "cloud of photons" is a space where photons are constantly be transmitted or sprayed. A continuous beam of light, in other words. Instead of calling it a "ray" or a "beam," they're describing it as a "cloud" of photons to make the point that something being shot through the beam will almost certainly bump into one of the ray's photons because that volume is always filled with photons, even if the photons aren't just floating around like fog particles in a cloud.
