       beams of light pulses. To this end, E
       ceramic scientist Ray Jaeger has he
       new system to make such fibers-
       powerful carbon dioxide laser.
       In the future, one hair-thin fiber migh

       long-distance calls. But many
       problems must still be solved. Ray
       tackled one of them - the problem
       of today's glass fibers, which
       contain impurities that absorb and
       weaken light beams. One impurity
       source is the conventional heaters
       used to melt glass rods that are
       drawn into fibers.
       Ray had to find a "clean" heat
       source that also would be precisely
       controllable, to assure uniform
       diameter throughout a mile-long
       fiber. Using his broad knowledge 01
