Excited-State Magnesium-Rare Gas Optical Collisions, Rosemary A. Lasell

Physics Theses & Dissertations

Polarization and intensity spectra have been obtained for excited-state magnesium (3s3p ¹P₁) - rare gas optical collisions. The magnesium was excited by a linearly polarized laser tuned to the 3s²1s₀ → 3s3p ¹P₁ atomic transition at 285 nm. A second linearly polarized laser was tuned near the 3s3p ¹P₁ → 3s5s ¹S₀ transition at 571 nm (experiment A) and near the 3s3p ¹P₁ → 3s4d ¹D₂ transition at 553 nm (experiment B). The polarization vector of the second laser was oriented either parallel or …
