Abstract

This paper numerical investigates the impact of reverse cross relaxation parameter on the pump efficiency using differential geometry of rate equations of thulium-doped (Tm-doped) tellurite material by examine certain reverse cross-relaxation processes, relating to series of population inversions. The primary aim of this research is to obtain a set of data that assists in predicting material performance in relation to a number of instances of the reverse cross-relaxation parameter to determine the optimum value of reverse cross- relaxation parameter. It is pointed out that a deep examination of the reverse cross-relaxation process (3F4,3F4,?3H6,3H4) was not available with the available data. The study demonstrates that reverse cross-relaxation may influence the pump efficiency of Tm-doped tellurite material. Therefore the research provides a set of parameters enabling evaluation of the reverse cross-relaxation process, thus illustrating how this process affects pump efficiency during a range of population inversions within differential geometry principle (0-50% in this study). The findings indicate that appropriate measurements of reverse cross-relaxation parameter may have a considerable effect on simulations for laser and amplifier devices. Moreover, the research shows that measurements of reverse cross-relaxation parameter for different glass types can facilitate identification of an appropriate host for various applications.
