Flea repport

Flea (French Laser Experiment Area) is both a test area for large lasers and 
a long term project to build a brain reader using quantum nondemolition X-ray 
holography.

The basic setting is a Michelson interferometer where long coherence X-rays 
make up to 1 million to and fro travels before exit. This ask for two 
gadgets: coherence length in the 100 000 km range and active, regenerative 
mirrors ( in fact, lasers with a gain power tunned to one). The coherence 
length implie the use of non-linear electromagnetic levels in nuclei as 
lasing medium.

To pump these levels, or more exactly broad, unstable, energy levels above 
them, I must have a powerful source of radiation in the Mev range. The 
traditional way to solve that problem has been to use nuclear explosion. 
Having not access to that technology, I plan to use up to one million 
entangled optical photons produced by a metal vapor laser.

The entanglement is produced by passing the laser beam between two nearby 
mirrors. Because the distance between mirrors is smaller than an atom, they 
are in fact interference paterns in an holographic picture.

That hologram is built in an photographic emulsion more than a foot thick, a 
product used for half a century in the detection of cosmic rays.

The metal vapor laser must deliver somthing as 120 MW of continuous power ( 
more in fact, because it works in pulse mode), the electric energy to feed it 
is at the level of a large nuclear plan. It has to be produced by a dedicated 
power source. The obvious choice is a magneto-hydrodynamics (MHD) burner. For 
simplicity, the primary energy source choosen is propane burning in high 
strength hydrogen peroxide.

Progress repport:

A stable (2 tons) table has been found for making holograms. Spin cast mirror 
concentrators for multi-beams optical laser has been experimented. A product 
for making bombs used in the cold forming of the MHD burner has been tested ( 
near catastrophe). It may be too a good way to solve social and political 
problems :-)
