N2 - The electronic structure of Cr4+-doped forsterite is studied using up-converted luminescence and excited-state excitation spectroscopy. Two metastable states with energies higher than the energy of the 3T2 lasing level are identified. The first, higher-lying state was identified as the 3T1(t2e) electronic state. Three lines were resolved at 26 424, 26 529, and 26 625 cm-1, corresponding to the spin-orbit-split zero-phonon line of the 3T1(t2e) state. The lifetime of this state was measured to be 395 ps. The second, lower-lying state is located at 12 847±90 cm-1 and is assigned to the 3T1(t22) state. Its lifetime is estimated to be of the order of a few hundred nanoseconds.
