High precision spectroscopic measurement using spectral hole burning technique with ultra-stable laser on Eu<sup>3+</sup> : Y<inf>2</inf>SiO<inf>5</inf> can be used to measure very small deformations in the crystal such as the ones arising due to quantum motion of nanoresonators. We present an experiment aiming at such high precision characterization.
We report on the current developments of an ultra-stable laser based on spectral hole burning spectroscopy of rare-earth doped crystal at cryogenic temperature. Narrow spectral holes and error signal have been demonstrated with a heterodyne method.
Frequency-locking a laser to a spectral hole in rare-earth doped crystals at cryogenic temperature has been shown to be a promising alternative to the use of high finesse Fabry-Perot cavities when seeking a very high short term stability laser (M. J. Thorpe et al., Nature Photonics 5, 688 (2011)). We demonstrate here a novel technique for achieving such… (More)
