But your exchange forces       me to ask if perhaps it might be possible to use the c-howitzer concept to       essentially pump an ion        laser. A shaped-charge nuclear blast would generate a plasma pulse that       threads an oscillating magnetic field, producing a laser pulse. This should       produce a yield not possible with current electron lasers because the energy       cost of generating the free        electrons is usually too high. Furthermore, at closer ranges, the plasma might       remain intact, so that it drills through right behind the laser beam.       >        > Keep in mond, this is not even back-of-the-envelope work. It is entriely       possible, and likely, that therre is no way this would work. I just wanted to       through it into the mix.              What kind of laser design would you use? For what I found about ion lasers,       they don't seem to be usable that way.              Assuming such a plasma-powered laser, additional losses would make it less       powerful than a pure Casaba Howitzer, however the laser itself may have better       range. So you are trading power for range.              Whether it is interesting probably depends on what technology and industry is       available (and what are your targets), as well as how bulky the whole thing       end up being. It may be more interesting to use a sub-par (more accessible)       X-ray mirror: less steps        gives more efficiency, and the short wavelength potentially gives better       range. Depending on the plasma-powered laser design, it may also be shorter       and/or lighter.       On the other hand, if the laser can use any wavelength, you could also use a       wavelength that won't be absorbed by air, for atmospheric/anti-surface use.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
