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 کاملPersistent spectral hole burning in an organic material for temporal pattern recognition
A broad-bandwidth persistent spectral hole-burning organic material is used as a fast optical processor that compares an input temporal-frequency profile with a recorded reference spectral shape. This patternrecognition procedure relies on a subpicosecond temporal cross-correlation process. The size of the phaseencoding spectral interval exceeds 1 THz. The storage material, the spectral encoder...
متن کاملProgrammable laser frequency stabilization at 1523 nm by use of persistent spectral hole burning.
Diode laser frequency stability of 2 kHz to 680 Hz over 20 ms to 500 s has been demonstrated at 1523 nm in the technologically important communication band by use of persistent spectral holes in the inhomogeneously broadened 4I15/2 --> 4I13/2 optical absorption of Er3+:D-:CaF2. Laser frequency stabilization was realized without vibrational or acoustical isolation of either the laser or spectral...
متن کاملUltra-fast temporal pattern recognition through a persistent spectral hole-burning filter
Cross-correlation of complex, picosecond-range, temporal shapes is demonstrated experimentally with the help of a filter recorded in an organic spectral hole-burning material.
