Spectral holeburning and the Stark and Zeeman effects in SrF2:Sm2+

Abstract

We have observed narrow (40 MHz) persistent spectral holeburning in SrF2:Sm2+ for Sm2+ ions in perturbed cubic sites. The transition studied is 7F0∌5D0 between the f-electron states. Stark effect measurements show a linear splitting with a coefficient of 0.006 MHz/V cm-1 and the splitting pattern shows that the site has C4V symmetry. The C4V perturbation is very weak and leads to unresolved splittings of cubic T1g levels of ∼2 cm-1. The nonlinear Zeeman effect was studied using holeburning and the coefficient of 1.04 Hz/G2 shows that the predominant magnetic coupling is in the ground state as found recently for CaF2:Sm2+. © 1985.
