Abstract

Summary form only given. Laser frequency stabilization to 200 Hz on a 5 ms time scale and to 1 kHz over 30 minutes has been demonstrated using persistent and transient spectral holes in inhomogeneously broadened resonances of Er/sup 3+/,D/sup -/:CaF/sub 2/, Er/sup 3+/:Y/sub 2/SiO/sub 5/, and Er/sup 3+/:KTiOPO/sub 4/ at cryogenic temperatures. Persistent spectral holes with lifetimes of weeks or longer provide a programmable and transportable secondary frequency reference, and kilohertz wide transient spectral holes provide excellent references at millisecond time scales appropriate for spectroscopy and coherent transient signal processing devices. This locking technique has significant applications to devices beyond the field of spectral hole burning.
