Spectral hole burning and selection of conformational substates in chromoproteins.
We investigated spectral holes burnt at 1.5 K into the origins of several tautomeric forms of mesoporphyrin IX-substituted horseradish peroxidase at pH 8 under pressures up to 2 MPa. From the pressure-induced lineshift the compressibility of the apoprotein could be determined. We found that the compressibility changed significantly when measured at different tautomer origins. It was concluded t...
متن کاملAnalytical description of spectral hole-burning effects in active semiconductors.
An analytical description of the effects of spectral hole burning on the optical properties of active semiconductor materials is developed for fields that are slow compared to intraband relaxation times. Nonlinear gain compression and four-wave mixing effects are discussed.
متن کاملSpectral hole burning and its application in microwave photonics
Spectral hole burning, used in inhomogeneously broadened emitters, is a well-established optical1 technique, with applications from spectroscopy to slow light2 and frequency combs3. In microwave photonics4, electron spin ensembles5,6 are candidates for use as quantum memories7 with potentially long storage times8. Here, we demonstrate long-lived collective dark states9 by spectral hole burning ...
متن کاملDetection of ultrasound-modulated diffuse photons using spectral-hole burning.
The lack of efficient detection techniques has so far prevented ultrasound-modulated optical tomography from achieving maturity. By applying a quantum spectral filter based on spectral-hole burning, one modulation sideband of the ultrasound-modulated diffuse photons can be efficiently selected while the DC and the other sidebands are blocked. This technique features a large etendue as well as t...
متن کاملPersistent 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...
