Steady-state energy transfer processes in laser-dye mixtures
Theoretical models to predict fluorescence of dye mixtures under steady state excitations, laser gain (and hence tunability) when these mixtures are used as lasing media are developed in this thesis. It is believed that the approach developed permits effective basic studies to be carried out under relatively simple steady state conditions, and permits relatively simple theoretical predictions to be made for the fluorescence of dye mixtures, and for laser gain when these mixtures are used as lasing media. It is also expected that the approach developed here will produce results of considerable interest to the operation of continuous output dye lasers, and result in improvements of output, efficiency, and threshold pump requirements. Finally, the validity and range of applicability of these models will be treated, by caring out a comprehensive and wider ranging set of comparisons between experimental data and theoretical predictions according to these models. This thesis will show that knowing absorption and emission spectra in individual dyes, it is readily possible to theoretically and accurately predict fluorescence spectra of dye mixtures, where radiative or/and non-radiative processes are the dominant energy transfer mechanisms. This may be practically used to predict fluorescence of dye mixture excitation sources. Furthermore since the concentration regimes involved are these generally applicable to laser action, it is then also feasible and practical to predict gain lineshape (hence tunability) for energy transfer dye lasers.
