Zeeman Effect Studies of theI75-I85Transition in CaF2:Dy2+

Zeeman effect studies of ${}_{}{}^5{}_{}{}^{}\mathrm{I}_7^{}{}_{}{}^{}$-${}_{}{}^5{}_{}{}^{}\mathrm{I}_8^{}{}_{}{}^{}$ fluorescent transitions of the Ca${\mathrm{F}}_2$: ${\mathrm{Dy}}^{2+}$ system were carried out. The symmetries and the spectroscopic splitting factors of a number of crystal field components were determined, and the transitions were found to be of magnetic dipole origin. Effects due to magnetic interactions among the lowest three crystal field components of the ground state were observed. The orientation dependence of the Zeeman pattern of the $|7\mathrm{}{T_1}^{\mathrm{}\left(2\right)\mathrm{}}〉\to |8\mathrm{}{T_2}^{\mathrm{}\left(2\right)\mathrm{}}〉$ laser transition is treated.
