Abstract

The temperature dependence of the R₁ linewidth in Al ₂O₃:Mn⁴⁺ is reported. Transient holes broaden rapidly from 2.5 to 40 K due to the one-phonon process between the E and 2A levels of the ²E excited state. The linewidth varies from 3 MHz at 2.5 K to 2640 GHz at 294 K and the line shifts by -1440 GHz. Above 50 K the two-phonon Raman process becomes dominant. The quadratic electron-phonon coupling constant is larger for Al₂O₃:Mn⁴⁺ compared to ruby, resulting in a stronger phonon sideband in Al ₂O₃:Mn⁴⁺. The best description of the linewidth data are yielded by a model using pseudo-local modes.
