Persistent spectral hole burning by simultaneous two-photon absorption
We show for the ®rst time persistent spectral hole burning by simultaneous absorption of two 1138 nm photons in an inhomogeneously broadened S1 S0 Qy transition of unstable photo-tautomer of chlorin in polymer ®lm at low temperature. Spectrally selective hole burning is achieved due to high (10%) quantum eciency of photo-transformation in that system and high peak intensity (tens of GW/cm) o...
متن کاملOptical Absorption and Fluorescence Spectral Analysis of Nd 3 + Doped Bismuth Boro - Silicate Glasses
Glasses having compositions 20B2O3.(79.5-x) Bi2O3.xSiO2 (10 ≤ x ≤ 40, mol%) doped with 0.5 mol% of Nd ions were prepared by melt quench technique. The amorphous nature of the glasses was confirmed by X-ray diffraction studies. The spectroscopic properties of Nd ions in borate bismuth silicate glasses as a function of bismuth oxide were investigated using optical absorption and fluorescence spec...

متن کاملSpectral diffusion in glasses under high pressure: A study by time-resolved hole-burning
We have studied optical dephasing and spectral diffusion of the S1←S0 0–0 transition of bacteriochlorophyll-a (BChl-a) in the glass 2-methyltetrahydrofuran ~MTHF! at ambient (Dp 50) and high pressure (Dp53.6 GPa) between 1.2 and 4.2 K by time-resolved hole-burning. The ‘‘effective’’ homogeneous linewidth Ghom 8 follows a power law dependence on temperature, Ghom 8 5G081aT , where G085G01G0 1G0 ...
متن کاملSlow light using spectral hole burning in a Tm3+-doped yttrium-aluminum-garnet crystal
We report on light slowing down in a rare-earth-metal-ion-doped crystal by persistent spectral hole burning. The absence of motion of the active ions, the large inhomogeneous broadening, the small homogeneous width, and the long lifetime of the hyperfine shelving states make this material convenient for the burning of narrow persistent spectral holes. Since the hole can be burnt long before the...
