چکیده
|
The optical absorption and emission intensity of luminescent and birefringent crystal erbawere examined from optical absorption data based on judd-ofelt theory. the three intensity parameters ω t (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 a r,radiative lifetime τ f,fluorescence branching ratios β c,and integrated emission cross sections ∑ have been calculated. in comparison with other er-doped luminescent crystals,erbamay find application in thin disk laser. © 2015 ming he et al.
