Abstract

Polarized differential absorption spectra of Cr⁴⁺- doped forsterite have been studied using a picosecond pump- probe technique. For pump beam and probe beam polarization parallel to the axis, an excited state absorption in the 450-800 nm region is observed and assigned to the ³T₂yields³T₁(³P) transition of Cr⁴⁺ ion. The lifetime of the ³T₁(³F) state is estimated to be less than 15 ps.
