Multiphonon relaxation in low phonon-energy Pr3+ glasses
Multiphonon relaxation in low phonon-energy Pr3+ glasses
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.

Abstract
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.
