Kopsavilkums

Absorption and luminescence spectra and luminescence kinetics of Yb have been measured in crystals of Yb,Er:LaSc₃(BO₃)₄ (LSB) for a wide region of variation of activator concentration. It has been established that an effective absorption cross-section of Yb³⁺ at the maximum of 982 nm is equal to 1.16×10^-20 cm². Effective absorption and emission cross-sections of Er³⁺at generation wavelength of 1555 nm are equal to σ_ab = 4.4×10^-21 and σ_em = 5.2×10^-21 cm^-2, respectively. ²F_5/2Yb³⁺→⁴I_11/2Er³⁺ energy transfer for dominating luminescence centers in Yb,Er:LSB is described satisfactorily by a dipole-dipole interaction with C_DA = 4.16×10^-39 cm^-6. Yb-Yb energy migration is very efficient and described by a hopping mechanism with C_DD = 3.5×10^-38 cm^-6, the quantum efficiency in Yb_0.15 (6.7×10²⁰ cm^-3), Er_0.015 (6.7×10¹⁹ cm^-3):LSB crystals has achieved 98%. Investigations of Yb,Er:LSB crystals have shown them to have necessary combination of properties to get an effective generation of 1.5 μm eye-safe radiation with laser diode pumping.
