Temperature dependence of the R 1 linewidth in Al 2 O 3 :Mn 4+ : A spectral hole-burning and FLN study

Riesen, Hans; Monks-Corrigan, Thomas; Manson, Neil

Description

The temperature dependence of the R1 linewidth in Al2O3: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 the2E 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...[Show more]

Transient holes broaden rapidly from 2.5 to 40 K due to the one-phonon process between the E and 2A levels of the2E 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 Al2O3:Mn4+. The best description of the linewidth data are yielded by a model using pseudo-local modes.
