Optical FID measurement of low temperature dephasing in Pr3+:LaF3
Abstract
The temperature dependence of the dephasing rate of the 1D2↔3H4 transition in 0.05% Pr3+ has been measured between 1.8 K and 4.5 K by optical free induction decay. One-phonon absorption between the two latest crystal field components of 1D2 is the dominant relaxation mechanism above ≈3 K. © 1979.
