LUMOGEN DYE-DOPED POLYMER OPTICAL FIBERS

摘要

Polymer optical fibers doped with Rhodamine B, Lumogen Orange (PBI-3) and N,/N′-Bis(3-pentyl)-4,11-bis(4-chlorlophenethyl)perylene-3,4,9,10-tetra-carboxyl-diimide (PBI-8) are presented. The experiments are carried out by longitudinally pumping the fiber samples with a Nd:YAG laser at 532 run. By comparing with Rhodamine B, the slope efficiencies of PBI-3 and PBI-8 are nearly improved for a factor of 2. Besides, the lasing threshold of PBI-3 and PBI-8 is approximately 80 % and 65 % better than that of Rhodamine B.
