Abstract :
The increase in upconversion rate in strongly erbium-doped fibres induced by an enhanced energy redistribution is investigated and explained in terms of spatial holeburning in the second-order excitation probability distribution. It is shown that the equalisation of decay curves, where the initial population has been prepared in different ways, is caused by an increased upconversion rate for closely located excited ions
