“…Orientation of the magnetic field was calibrated with microwave spectroscopy [16]. In addition, the ODTbeam polarization was cleaned by a polarization beam splitter in combination with a 4  plate and thus the ellipticity parameter, * uu   , was less than 0.03 during all the measurements.…”

I. ABSTRACTDipolar atoms have unique properties, making them interesting for laser cooling and quantum simulations. But, due to relatively large orbital momentum in the ground state these atoms may have large dynamic tensor and vector polarizabilities in the ground state. This enables the formation of spindependent optical traps. In this paper real part of tensor and vector dynamic polarizability was experimentally measured and compared to theoretical simulation. For an optical dipole trap operating around 532.07 nm tensor, polarizability was found to be 145 53 a.u.  and vector was 680 240 a.u. The measurements were compared with simulations, which were done based on the known set of levels from a thulium atom. The simulations are in good agreement with experimental results. In addition, losses of atoms from the dipole trap were measured for different trap configurations and compared to the calculated imaginary part of vector and tensor polarizabilities.
