Abstract
Preliminary observations and measurements of increased relaxation spee ds in resonantly enhanced nonlinear systems are demonstrated. The effe ct is observed using a neodymium-doped twin-core fibre interferometer, and uses stimulated down-pumping of the F-4(3/2) metastable state in neodymium. The relaxation time has been reduced from approximately 390 mus to less than 120 mus, and it is shown that the reduction is depen dent on the power of the down-pumping source.
