摘要

In this paper, we report on the 2.7 μm mid-infrared emission performance under 974 nm excitation in Pr~(3+)/Er~(3+) co-doped CaYAlO_4 crystal. It is found that with the presence of Pr~(3+) ion, the green, red up-con-version and the near-infrared emission are almost quenched. Besides, the laser lower level ~4I_(13/2) depopulated much faster than the upper level ~4I_(13/2). That indicates the population inversion become easier and the self-saturation for the transition ~4I_(13/2)→ ~4I_(13/2) of Er~(3+) in become weaker than that in Er~(3+):CaYAlO_4 crystal. The energy transfer mechanism and the energy transfer coefficients are calculated and discussed. All the results imply that Pr~(3+) codoping benefits to achieving 2.7 μm laser in Pr~(3+)/Er~(3+):CaYAlO_4 crystal.
