We present characterization of the hyperfine and quadrupole interactions of praseodymium in La 2 ( WO 4 ) 3 . The hyperfine structure of the H 4 3 ( 0 ) → 1 D 2 ( 0 ) transition is calculated from a crystal-field analysis and is compared to experim

With all-optical means, the nuclear spin coherence lifetime is measured for the first time in a crystal doped with low-concentration thulium. A novel Raman echo scheme is demonstrated. The hyperfine splitting is varied over a 15 MHz-wide range with t

Automatic classification of variability is now possible with tools like neural networks. Here, we present two neural networks for the identification of microlensing events -- the first discriminates against variable stars and the second against super

Electron paramagnetic resonance spectroscopy of rare earth ions in crystals is an interesting tool to analyze the hyperfine structure of the rare earth ground state. This can be useful for coherent spectroscopy and quantum information applications wh

Ancient geological materials are likely to be contaminated through geological times. Thus, establishing the syngeneity of the organic matter embedded in a mineral matrix is a crucial step in the study of very ancient rocks. This is particularly the c

We studied the hyperfine structure and hyperfine coherent properties of the H-3(4)(0)-> D-1(2)(0) transition of Pr3+ ions in a tungstate single crystal La-2(WO4)(3) by hole-burning and photon-echo techniques. This work is motivated by the search of a

We have studied a rare-earth-doped crystal, Pr3+:La-2(WO4)(3), which exhibits a high magnetic-moment density. Although the latter favors rare-earth dephasing, a nuclear-spin coherence lifetime of 250 mu s has been observed, as well as electromagnetic

In this paper, we investigate a new medium for quantum light storage in crystals. Indeed, ${\text{Tm}}^{3+}:{\text{Y}}_{2}{\text{O}}_{3}$ exhibits all the features that are currently considered crucial for a storage protocol. First, optical measureme

A thulium-doped crystal is experimentally shown to be an excellent candidate for broadband quantum storage in a solid-state medium. The nuclear spin coherence is optically excited, detected, and characterized in such a crystal. The lifetime of the sp
