Comic book fans have long dreamed of emitting a powerful beam from their eyes like superhero Cyclops of the X-Men.

This caused a green laser to be beamed out of the other end that was visible to the human eye.
In the future ‘living lasers’ could be produced inside live animals which would give unprecedented detail on scanners.
They could also have applications for computing and electronics and one day allow doctors to treat cancers by lasering inside the body rather than from the outside
