Multiphonon relaxation in low phonon-energy Pr3+ glasses

Naftaly, M., Jha, A., Hewak, D.W., Brocklesby, W.S., Samson, B.N. and Payne, D.N. (1993) Multiphonon relaxation in low phonon-energy Pr3+ glasses At QE-11: 11th UK National Quantum Electronics Conference, United Kingdom.

Record type: Conference or Workshop Item (Paper)


Recently there has been a great deal of interest in optical fibre amplifiers and lasers operating in the 1.3 µm wavelength telecommunications window; for this application, Pr3+-doped low phonon-energy glasses have attracted a great deal of attention. In these glasses the lifetime of the metastable level is dominated by non-radiative relaxations, of which the two most important processes are multiphonon decay and concentration quenching. The doping levels are thus limited by the need to avoid the latter; while the former effectively determines the lifetime in lightly-doped glasses. The aim of this work has been to investigate the crucial parameters which control the multiphonon decay rate in low phonon-energy glasses and their dependence on glass constituents.
