Er3+:(Sr0.7Ca0.3)3Y(BO3)3 crystal with dimensions of 2134 mm3 has been grown by the Czochralski method. The polarized spectral properties were investigated. Based on the Judd-Ofelt theory, the oscillator strength parameters, transition probability, fluorescence branching ratio and radiative lifetime were estimated. The stimulated emission cross-sections of Er3+:(Sr0.7Ca0.3)3Y(BO3)3 crystal were calculated to be 21.010-21cm2 at 1541nm for the π-polarization and 2.2510-20cm2 at 1536nm for the σ-polarization. The quantum efficiency ηc, Er3+:(Sr0.7Ca0.3)3Y(BO3)3 crystal is 40.3%. In comparison with Er3+:Sr3Y(BO3)3 crystal, the spectral properties of Er3+:(Sr0.7Ca0.3)3Y(BO3)3 crystal are better than that of Sr3Y(BO3)3 crystal. The investigated results showed that after the Ca2+ ion partly substitute for Sr2+ ion in Sr3Y(BO3)3 crystal to form the (Sr0.7Ca0.3)3Y(BO3)3 solid solution, it can greatly improve the quantum efficiency of Er3+:(Sr0.7Ca0.3)3Y(BO3)3 crystal. Therefore, Er3+:(Sr0.7Ca0.3)3Y(BO3)3 crystal may be become a 1.55 m laser crystal materials..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
