Growth and spectral properties of Nd 3+-doped Sr 3Y(BO 3) 3 crystal

Abstract

A new crystal of Nd 3+:Sr 3Y(BO 3) 3 with dimension up to ∅ 25×35 mm 2 was grown by Czochralski method. Absorption and emission spectra of Nd 3+: Sr 3Y(BO 3) 3 were investigated . The absorption band at 807 nm has a FWHM of 18 nm. The absorption and emission cross sections are 2.17×10 −20 cm 2 at 807 nm and 1.88×10 −19 cm 2 at 1060 nm, respectively. The luminescence lifetime τ f is 73 μs at room temperature
