We report on persistent spectral hole-burning and fluorescence-excitation spectroscopy in heavy-dose (3 x 10(20) n/cm(2)) neutron-irradiated and annealed sapphire using a Ti:Sapphire ring laser in single-frequency and broad-band operation. The optimum conditions for hole burning were obtained after annealing the crystals to 400 degrees C. Holes have been detected in the near-infrared spectral range between 745 and 795 nm. At 1.5 K, the narrowest hole widths were approximately 2 GHz, so that about 10(4) holes can be burnt in this spectral region. Besides the storage density in the wavelength dimension, the coefficient describing the electric-field-induced filling of a spectral hole also rises by more than one order of magnitude as compared to crystals with low neutron-irradiation dose.
