possible.  I had thought of that: you could run the cables to a single head
containing a collimator.  Even then, the cables might need to be replaced every
so often.

The advantage would be not having to keep your collector next to your sintering
machine.  Optical Fibre only loses 5% intensity per 1km, which works out to 1%
every 200m, so with relatively short distances, it shouldn't matter very much.

if you could use the light to drive an actual laser, it might be even more
efficient.
