This paper reports the growth,X-ray diffraction and spectroscopy of Nd~(3+):Sr_3Gd_2(BO_3)_4 crystal.A Nd~(3+):Sr_3Gd_2(BO_3)_4 crystal with dimensions ofφ20×45 mm~3 has been grown by the Czochralski method.Nd~(3+):Sr_3Gd_2(BO_3)_4 crystal belongs to the orthorhombic system,space group Pnma(D_(2h))with a=0.7401,b=1.604 and c=0.8755 nm.The absorption and emission spectra of Nd~(3+):Sr_3Gd_2(BO_3)_4 were investigated.The absorption cross sectionσ_a is 3.11×10~(-20)cm~2 at 808 nm. The absorption transition at 808 nm has an FWHM of 14 nm.The luminescence lifetimeτ_f is 51.7 us.The emission cross sectionσ_e at 1064 nm wavelength is 1.09×10~(-19)cm~2.
This paper reports the growth, X-ray diffraction and spectroscopy of Nd ~ (3 +): Sr_3Gd_2 (BO_3) _4 crystal.A Nd ~ (3 +): Sr_3Gd_2 (BO_3) _4 crystal with dimensions ofφ20 × 45 mm ~ 3 has has been grown by the Czochralski method.Nd ~ (3 +): Sr_3Gd_2 (BO_3) _4 crystal belongs to the orthorhombic system, space group Pnma (D_ (2h)) with a = 0.7401, b = 1.604 and c = 0.8755 nm. The absorption transition at 808 nm has an FWHM of 3.11 × 10 ~ (-20) cm ~ 2 at 808 nm. The absorption transition of Nd ~ (3 +): Sr_3Gd_2 (BO_3) _4 were investigated. 14 nm. The luminescence lifetime τ_f is 51.7 us. The emission cross section σ_e at 1064 nm wavelength is 1.09 × 10 ~ (-19) cm ~ 2.
