Spectral hole burning is reported for the trivalent thulium ion with measurements on the ³H₆(1) ↔ ³H₄(1) transition of LaF₃:Tm³⁺ and two sites (A and B) of CaF₂:Tm³⁺ at 1.5 K. Hole burning occurs by population storage in the metastable ³F₄ level. The holes were scanned by an electric-field ramp applied directly to the sample, the frequency being calibrated by burning multiple holes with a frequency-modulated laser. This yielded the hole widths as well as the Stark coefficients for the transition studied, which are 8.3 kHz/V cm^-1 parallel to the C₂ axis (LaF₃:Tm³⁺) and for CaF₂:Tm³⁺ are 25 kHz/V cm^-1 (site A), and 4.6 kHz/V cm⁻¹ (site B) for fields along the (001) direction. From the polarization behavior of the holes, the sites in CaF₂ are assigned to the F^--compensated C_4ν and C_3ν sites, respectively.
