Well, I've been interested in lasers for quite a while-- but the FEL is really what fascinates me. I haven't been able to find much technical information on the internet about it, and my library is decrepid. But, still, never-the-less, I believe, just like any other laser, that it can be built in my garage. I know the basics of how it works. 1) Does anyone know where technical data on FEL design/theory is? 2) Would would be the mininum amount of acceleration that would have to be achieved for coherent light- and what would be the best way of achieving this (probably cyclotron- but my acceleration skills are rusty)? 3) How much would the electron beam have to be undulated to attain coherent light? Thankyou.
