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:TmHo:YAG and Cr:TmYAG 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.
