Temperature dependence of low-lying phonon dephasing by ultrafast spectroscopy (optical Kerr effect) in Ag β-alumina and Tl β-alumina

Dephasing processes for low-lying phonons of Ag+ and Tl+ beta-alumina were observed in the time domain using the femtosecond pulse laser in the temperature range of 15-350 K. The dephasing dynamics associated with the time evolution of the vibrational coherence state can be directly identified with...
