摘要：

Minimization of internal degrees of freedom is an important step in the cooling of atomic species to degeneracy temperature. Here, we report on the loading of 6 x 10(5) thulium atoms optically polarized at maximum possible magnetic quantum number m(F) = -4 state into dipole trap operating at 532 nm. The purity of polarizations of the atoms was experimentally verified using a Stern-Gerlach-type experiment. Experimental measured polarization of the state is m(F) = -3.91 +/- 0.26.
