Abstract
We observed photon-gated spectral hole burning in Pr:YAG and assigned the hole-burning mechanism to selective photoionization of trivalent p raseodymium. Gated holes were observed in absorption lines to the two lowest components of the D-1(2) manifold. At 1.4 K the gating ratio is in excess of 1.5 x 10(4). Strong competition from the transient mecha nism of optical pumping of hyperfine levels occurs below 6 K. (C) 1996 Optical Society of America
