Abstract

Investigation results of effective population of states of 5d-configuration of Ce³⁺ ions by energy transfer from Pr³⁺ ions in LiY_0.3Lu_0.7F₄ (LYLF) crystals are discussed. The real concentrations of Pr³⁺ and Ce³⁺ ions in LYLF crystals are determined. Such parameters as excited 4f-5d state photoionization cross-section of Pr³⁺ ions, ground state cross-section of Ce³⁺ ions at 266 nm wavelengths and energy transfer coefficients of energy transfer from Pr³⁺ to Ce³⁺ ions were estimated. The results of pump-probe experiments on 5d-4f transitions of Ce³⁺ ions in LYLF crystals are presented. The optimal parameters for getting maximal gain on 5d-4f transitions of Ce³⁺ ions were determined by mathematical modeling.
