Optical Transition Probabilities of Er3+ Ions in ErBa3B9O18 Crystal
The optical absorption and emission intensity of luminescent and birefringent crystal ErBa3B9O18 were examined from optical absorption data based on Judd-Ofelt theory. The three intensity parameters Ωt (t=2,4,6) are 3.10 × 10−20, 0.87 × 10−20, and 1.80 × 10−20 cm2, respectively. From the obtained in...

| Summary: | The optical absorption and emission intensity of luminescent and birefringent crystal ErBa3B9O18 were examined from optical absorption data based on Judd-Ofelt theory. The three intensity parameters Ωt (t=2,4,6) are 3.10 × 10−20, 0.87 × 10−20, and 1.80 × 10−20 cm2, respectively. From the obtained intensity parameters, the radiative probabilities Ar, radiative lifetime τf, fluorescence branching ratios βc, and integrated emission cross sections ∑ have been calculated. In comparison with other Er-doped luminescent crystals, ErBa3B9O18 may find application in thin disk laser. |
