Abstract Details

2008, Master of Science, Miami University, Physics.
We studied the effect of depolarization of the atomic cesium in the 6p2P3/2 level by using two-photon two-color nano-second pulse lasers in collision with krypton buffer gas at various pressures. We used linearly polarized dye lasers at 852.112 nm and at 603.409 nm wavelengths for the 6s2S1/2 to 6p2P3/2 to 10s2S1/2 transition.Excitation of ground state cesium atoms by linearly polarized light produces an electric quadrupole moment in the excited state. The polarization degree of the emission spectra was measured and was used to calculate the alignment (electric quadrupole moment) in the 6p2P3/2 state. Further, the collisional depolarization effect on the linear polarization was measured at various buffer gas pressures from the spectra and it showed a strong pressure dependence on the polarization spectrum. Finally we extracted the collisional depolarization cross-section of the 6p2P3/2 Cs atoms in collision with Kr from the measured linear polarization spectrum.
