Abstract

The up-converted fluorescence of Pr³⁺ in the Pr³⁺:GMO crystal is observed at 490 nm and 499 nm(³P₀->³H₄) when 1D2 level is excited by 595 nm dye laser beam. Both up-converted and ordinary fluorescence show the same lifetime of 200 ns. It is suggested that the sequential two-photon excitation process (STEP) is dominant in the up-conversion mechanism.
