Abstract
Abstract Spectroscopic characterization of Czochralski grown Ho(0.2%–4%):PbWO 4 crystals were performed over 0.2–8 μm spectral range. Polarized optical absorption, emission and kinetics of fluorescence of 5 I 8 ⇔ 5 I 7 holmium transitions were studied over 20–300 K temperature interval. The lifetime of 5 I 7 state in the Ho(0.5%):PbWO 4 crystal was measured to be 5.0 ms. The stimulated Raman scattering at 2.5 μm was studied under 1.7 and 2.0 μm excitation.
