Abstract

NdAl₃(BO₃)₄ single crystals with different concentrations of Yb³⁺ were grown using the top seeded solution growth method. The absorption spectra of the grown samples were recorded at room temperature and analyzed using the standard Judd-Ofelt theory. Influence of Yb³⁺ concentration on the Nd³⁺ absorption properties was studied. Variation of the Nd³⁺ oscillator strengths with changing Yb³⁺ concentration suggests significant role of the Yb-Nd energy transfer in the formation of the absorption spectra. Following the absorption spectra we illuminated the investigated crystals at 532 nm absorption line to observe the changes of the two-photon absorption (TPA). We observed substantial increase of the TPA with the increased power of the illuminating laser which was proportional to the Yb content.
