Abstract

Excited-state absorption and stimulated-emission measurements of Mn5+-doped Sr5(VO4)3F were made with a pump-and-probe technique. Strong excited-state absorption bands were observed, corresponding to the transitions from the  1E(1D) metastable level to higher-lying singlet levels. The stimulated emission from the  1E(1D) level to the  3A2(3F) ground state is overlapped by a tail of the  1E(1D) 1T2(1D) excited-state absorption band. The cross section of the  1E(1D) 1T2(1D) transition at 1161 nm is (1.4±0.3)×10-20 cm2 for Ec and (2.4±0.5)×10-20 cm2 for Ec. The ratio between the excited-state absorption and the stimulated-emission cross section at 1161 nm is 0.52 for Ec and 1.82 for Ec. Therefore laser emission is expected to be inefficient in Ec polarization and not to be possible in Ec polarization. The crystal field parameters in the cubic field approximation were determined to be Dq=1134 cm-1, B=356cm-1, and C=2918cm-1, giving Dq/B=3.19 and C/B=8.20.
