As the magnets wiggle the electron beam, it imparts energy to the laser photons.

I have wondered if the FF could power a free alpha laser instead, where the negative charged electrons are substituted and replaced by the positive alpha beam coming out of the FF reactor. It would work in much the same way : the alpha particles are wiggled by magnetic fields, transferring their energy over to the laser photons …… thereby amplifying it.

But like Lerner said, the United States, Russia, China, Japan, Great Britain, etc. already have enough weapons to destroy the entire world many times over. Who really needs more ?

However, I can see some peaceful applications of a free alpha laser driven by the energetic alpha beam of the FF reactor. Perhaps a powerful pulsed beam could be an alternative way to blast a road tunnel or a railroad tunnel through a mountain or something.

I know this may be drifting a little off the main subject here, but I just decided to mention this as still yet another possible application of the DPF in the future.

Or use the laser for some of the solar sail space propulsion concepts?
