Abstract

The effect of pressure on the spectrum and energy transfer properties of Cr3+:Tm3+:YAG has been considered. The results of cw and pulsed luminescence experiments are reported. The high pressure cw experiments demonstrate the existence of 1G4 → 3H5 emission from Tm3+. We believe this emission is also present in Tm3+:YAG at ambient pressure and has been previously misassigned. High pressure pulsed luminescence studies indicate a lengthening of the lifetime of Cr3+ in Cr3+:Tm3+.YAG and indicate that the rate of energy transfer from Cr3+ to Tm3+ decreases with increasing pressure. We interpret this result in terms of a destabilization of the 4T2 level of Cr3+ with increasing pressure.
