Paper Abstract

Spectroscopic studies using laser induced fluorescence and numerical modelling of energy transfer and back transfer mechanism are reported in Er:Tm:Ho:YLF, Cr:Tm:Ho:YAG and Cr:Tm:YAG laser crystals at various temperatures (10 K - 300 K). Direct energy transfer from Tm3+ excited states to Ho3+ 5I7 emitting level was observed and analyzed both in YAG and YLF. Further analysis of Cr3+ and Tm3+ time-dependent emission curves indicate a strong correlation of chromium- thulium pairs. Pulsed operation of holmium laser at high temperature will be presented.
