    "abstract": "We have frequency stabilized a Coherent CR699-21 dye laser to a transient\nspectral hole on the 606 nm transition in Pr^{+3}:Y_2SiO_5. A frequency\nstability of 1 kHz has been obtained on the 10 microsecond timescale together\nwith a long-term frequency drift below 1 kHz/s. RF magnetic fields are used to\nrepopulate the hyperfine levels allowing us to control the dynamics of the\nspectral hole. A detailed theory of the atomic response to laser frequency\nerrors has been developed which allows us to design and optimize the laser\nstabilization feedback loop, and specifically we give a stability criterion\nthat must be fulfilled in order to obtain very low drift rates. The laser\nstability is sufficient for performing quantum gate experiments in\nPr^{+3}:Y_2SiO_5.",
