The optical properties of the rare elements Tm 3+, Ho 3+ and Yb 3+ were systematically investigated in various glasses. The Tm 3 + doped aluminozircofluoride glass shows higher quantum efficiency, longer lifetime and stronger fluorescence intensity than Tm 3 Γ· doped YSGG crystal and other Tm 3 Γ· dop

An energy transfer from chromium towards thulium ions is pointed out in LiNbO, : MgO under laser excitation into the 4T, chromium absorption band. Its quantum yield was found to be 75% in the studied Cr-Tm co-doped sample. The transfer is partly radiative and partly non-radiative and is an average o
The absorption and emission spectra of Tm 3+ -and Ho 3+ -doped Ba 2 NaNb 5 O 15 crystals have been measured in the 1.5-2 lm region. The lifetimes of the lowest excited states have been measured at 10 and at 298 K. The cross sections of the (Tm) 3 F 4 M 3 H 6 and (Ho) 5 I 7 M 5 I 8 transitions have b
