Abstract

We observed photon-gated spectral hole burning in Pr:YAG and assigned the hole-burning mechanism to selective photoionization of trivalent praseodymium. Gated holes were observed in absorption lines to the two lowest components of the ¹D₂ manifold. At 1.4 K the gating ratio is in excess of 1.5 × 10⁴. Strong competition from the transient mechanism of optical pumping of hyperfine levels occurs below 6 K.
