摘要：

Spectroscopic characterization of Czochralski grown Ho(0.2%-4%):PbWO4 crystals were performed over 0.2-8 mu m spectral range. Polarized optical absorption, emission and kinetics of fluorescence of I-5(8) double left right arrow I-5(7) holmium transitions were studied over 20-300 K temperature interval. The lifetime of I-5(7) state in the Ho(0.5%):PbWO4 crystal was measured to be 5.0 ms. The stimulated Raman scattering at 2.5 mu m was Studied under 1.7 and 2.0 mu m excitation. (C) 2008 Elsevier B.V.
