Optical Excitation of Nuclear Spin Coherence in Tm3+:YAG

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

Dual-Frequency Laser at 1.5 µm for the Generation of High-Purity Microwave Signals

We describe the stabilization of a dual-frequency laser on an external reference and on fiber delay lines. Low phase noise (-107 dBrad²/Hz at 10 kHz) beatnotes tunable from 2 to 6 GHz are demonstrated.

Branching ratio measurement of a "Lambda" system in Tm3+:YAG under magnetic field

A three-level Lambda system in Tm3+ doped YAG crystal is experimentally investigated in the prospect of quantum information processing. Zeeman effect is used to lift the nuclear spin degeneracy of this ion. In a previous paper [de Seze et al. Phys…
