A crystal of Nd 3+ :Sr 3 Gd(BO 3 ) 3 with dimension of ϕ25×30mm 3 was grown by the Czochralski method. The polarized absorption and emission spectra of Nd 3+ :Sr 3 Gd(BO 3 ) 3 crystal were measured at room temperature. The absorption cross sections σ a are 3.43×10 −20 cm 2 at 807nm for π-polarization and...
A transparent Yb 3+ :Sr 3 La 2 (BO 3 ) 4 crystal with dimension ϕ20×25mm 3 was grown by Czchoralski method. Yb 3+ :Sr 3 La 2 (BO 3 ) 4 crystal congruently melts at 1337.5°C. The segregation coefficient of Yb 3+ in Yb 3+ :Sr 3 La 2 (BO 3 ) 4 crystal is 0.65. The absorption...
