Abstract :
A technique based on selectively excited fibre impurity luminescence (SEFIL) has been developed and successfully applied to the quantitative analysis of Pr3+, Nd3+ and Fe3+ in heavy metal fluoride glass optical fibres. With fibre standards, SEFIL provides accurate analysis at impurity levels well below the requirements for long-distance fibre applications.
