US Air Force prototypes a PHaSR
The Personnel Halting and Stimulating Response uh, device, about the size and weight of an M60, fires a pulse of light that temporarily blinds anybody in the beam. It seems to be a crowd-control device more than anything else, but has a beam rather than a cone area of effect (and as noted at Gotta Have One) may just be thwarted by a decent pair of polarizing sunglasses. Certainly, despite the name, not something you can nail somebody in the back with and have them be unconscious until the plot demands otherwise.
