Abstract

Persistent spectral hole-burning (PSHB) is a versatile tool to study Stark effect in solids where impurity spectra is strongly inhomogeneously broadened. At liquid helium temperatures impurity homogeneous zero-phonon line widths are small (γ_hom~10^–2-10^–4cm^–1) and narrow holes can be burnt in the inhomogeneous distribution by illumination with narrow band laser(Δν_laser < γ_hom) U1- Stark effect alters the shape of narrow spectral holes depending on the Stark shift (splitting) of impurity energy levels, orientation of the impurities, strength and orientation of the electric field, as well as on the properties of the matrix [2].
