Spectral 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 کاملSpectral 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 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 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 کاملBroadband radio-frequency spectrum analysis in spectral-hole-burning media.
We demonstrate a 20 GHz spectrum analyzer with 1 MHz resolution and >40 dB dynamic range using spectral-hole-burning (SHB) crystals, which are cryogenically cooled crystal hosts lightly doped with rare-earth ions. We modulate a rf signal onto an optical carrier using an electro-optic intensity modulator to produce a signal beam modulated with upper and lower rf sidebands. Illuminating SHB cryst...
