magnetic field

abstract: 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. Rev. B, 73, 85112 (2006) we measured the gyromagnetic
tensor components and concluded that adequate magnetic field orientation could
optimize the optical connection of both ground state sublevels to each one of
the excited state sublevels, thus generating Lambda systems. Here we report on
the direct measurement of the transition probability ratio along the two legs
of the Lambda. Measurement techniques combine frequency selective optical
pumping with optical nutation or photon echo processes.
