Abstract

Persistent spectral hole burning has been observed in CaF₂:Sm²⁺ and originates from photoionization of the Sm²⁺ ion. This represents a new class of persistent hole-burning materials. We have used hole burning to measure the nonlinear Zeeman effect of the ⁷F₀A_1g → A_1u transition at 695.8 nm with a resolution of ∼100 MHz. We find a nonlinear coefficient of 0.93 Hz/G², which is close to the value of 1.0 Hz/G² calculated for the ⁷F₀–⁷F₁ interaction. This shows that the dominant contribution to the nonlinear Zeeman effect comes from the ground state.
