Abstract

PWO crystals were grown using the Czochralski method with concentrations from 0.2% to 4%. The polarized optical absorption, emission, and kinetics of fluorescence were measured at room temperature and low (14K) over a spectral range of 0.2 to 3 microns. The spectroscopic data were then used to calculate the absorption and luminescence cross sections. The maximum absorption cross at ⁴I_13/2→⁴I_15/2 transition section was calculated to be σ=8.0x10^-21 cm² at 1500 nm and E||z polarization of incident light. The measured luminescence lifetime at this transition was 5.6 ms.
