Programmable 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 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 کاملObservation of laser-jitter-enhanced hyperfine spectroscopy and two-photon spectral hole-burning
Ž . We have observed laser-jitter-enhanced high-resolution spectra of three hyperfine states in the ground level H of 4 Pr :Y SiO using coherent population trapping and phase-correlated four-wave mixing. We have also observed optical 2 5 Raman pulse excited two-photon spectral hole-burning. The observed high-resolution spectra are due to a laser-jitter-suppressed Raman coherence window in an in...
متن کاملPulsed ultrasound-modulated optical tomography using spectral-hole burning as a narrowband spectral filter.
We applied a submegahertz nonlinear optical filter afforded by a cryogenically cooled spectral-hole burning crystal to ultrasound-modulated optical tomography. Our experimental results show that this technique, having the largest etendue among all available ultrasound-modulated optical tomography techniques and being immune to speckle decorrelation, offers potential for imaging in vivo and form...
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...
