Abstract

We report the first observation of room-temperature persistent spectral hole-burning in glass. The holes were burned in the 7F0→5D0 line of Sm2+ ions in fluorohafnate glass.

We report the first observation of spectral hole burning in the spectra of impurity centers at room temperature. The persistent holes are burned in the 5D17F0 (632 nm) and 5D0-7F0 (690 nm) transitions of Sm2+ ions in the title compound.

Wavelength Dependence of Persistent Spectral Hole Burning in Sm2+-Doped Fluoride Glasses

We reported the first observation of room-temperature persistent spectral hole burning in Sm2+-doped fluoride glass in the last conference [1]. Room-temperature hole burning had been also observed in Sm2+-doped crystals [2]. We found considerable differences in the hole-burning characteristics between Sm2+-doped glasses and Sm2+-doped crystals: The burning-laser-intensity dependence is approximately linear, and no antihole is observed around the hole burned in Sm2+-doped glasses [3]. More detailed experimental studies are needed to clarify the mechanism of the hole burning in this glass and to explore more efficient hole-burning systems. In this paper, we report several experimental results related to wavelength dependence of the hole burning process.

Room-temperature persistent spectral hole burning in Sm^2+-doped fluoride glasses

Atusi Kurita, TETSURO IZUMITANI, Michimasa Matsukawa +1 more

Persistent spectral hole burning is observed in Sm(2+)-doped glasses at room temperature. The holes are burned in the (7)F(0) ? (5)D(0), (5)D(1) lines of the Sm(2+) ions in three kinds of fluoride glass. The dependence of the burning efficiency on the sample and on the burning intensity is measured. The intensity dependence is approximately linear, and no antihole is observed around the burned hole. The hole-burning mechanism is discussed. The temperature dependence of the homogeneous width is also measured.

Room-temperature persistent hole burning of Sm^2+ in oxide glasses

Persistent spectral hole burning in Sm2+-doped borate glasses is observed at room temperature. The possible number of holes is approximately five times larger than in halide glass systems because of the larger inhomogeneous linewidth and smaller hole width of borate glass. In this system the photoionization of trapping electrons other than Sm ions at a site is likely to be dominant because of the absence of an antihole adjacent to the hole.
