Unique high-bandwidth UV fiber delivery system for the OMEGA diagnostics applications

A special fiber-optic signal delivery system for 351-nm pulse-shape measurements has been developed in the contest of a large laser fusion facility. To deliver a sufficient signal and preserve an overall bandwidth of >33 GHz over a distance of /spl sim/15 m, a seven-fiber bundle of gradient-index fiber was developed, fabricated, and tested, and is now applied in routine operation.
