Abstract:

The ordinary fluorescence of Er3 in Y2O3 and LaF3 crystals is observed when the crystals are excited with 6328A He-Ne laser radiation. From the linear power dependence of the 6800A fluorescence and the quadratic power dependence of the 5640 and 3900A fluorescence on the 6328A excitation, a single photon excitation for the 6800A fluorescence and a double-photon stepwise excitation for the 5640 and 3900A fluorescence were proposed. The calculated photon flux of the 5640A fluorescence based on the two-photon stepwise excitation agrees with the estimated observed value. Author
