PHOTON GATED HOLE BURNING IN THE7F0?5D2ABSORPTION OF BaCIF : Sm2+

J. C. Vial, R. M. Macfarlane

Spectral hole burning in solids is a selective bleaching of a small portion of an inhomogeneously broadened optical transition by a laser. In the photon gated holeburning process spectral holes are burned in two steps. The first is provided by a narrow band laser resonant with the inhomogeneously broadened transition and the second (gating) can be initiated by a broad band light source. Photon gated spectral hole burning was reported recently in 7F0→5D0 and 7F0→5D1 absorption lines of Sm2+ in BaClF(1). In this poster we report on the spectral holeburning behaviour of 1F0→5D2 transition. We found that even in absence of additional light source for gating, permanent holes can be burned. This self gating behaviour is consistent with the observation that the optimum frequency following 5D0 excitation is ≈ 22 000cm-1 so that two photons of energy 5D2 - 7F0 are sufficient to produce photoionisation. We have analysed the light intensity dependance of hole area and a simple model indicate that the electron transfer following the photoionisation is strongly dependant on the ion - electron trap distance.Spectral hole burning in solids is a selective bleaching of a small portion of an inhomogeneously broadened optical transition by a laser.

Holographic Hole Burning

Alois Renn, Stefan Bernet, Bern Kohler +1 more

Persistent spectral hole burning (PSHB) [1] allows for frequency selective recording of holograms and opens interesting prospects for high density optical information storage and processing. When hole burning is performed with the interference pattern of two crossed laser beams a spectrally narrow hole is created in an inhomogeneously broadened absorption band and simultaneously the spatial fringe pattern is recorded as a modulation of the hole depth. During reconstruction of the hologram diffraction from this spatial fringe pattern occurs, reflecting the changes of the absorption coefficient and the refractive index introduced by the spectral hole [2].Persistent spectral hole burning (PSHB) [1] allows for frequency selective recording of holograms and opens interesting prospects for high density optical information storage and processing.
