Abstract :
A detailed understanding of rare-earth-doped optical fibre lasers and amplifiers requires a knowledge of the absolute concentration and dopant ion distribution in the fibre core. Measurements are analysed of the concentration dependent relaxation rate of the 3P0 state of praseodymium, spatially resolved by confocal microscopy, to give an absolute measure of the concentration profile in praseodymium-doped fluorozirconate optical fibre
