Autler-Townes splitting and AC Stark shift in a diatomic alkali vapor

Summary form only given. Autler-Townes (AT) splitting and the AC Stark shift in a molecular gas have only recently been investigated. In our work we utilize a CW optical-optical double resonance (OODR) excitation scheme to measure the Doppler-free AT splitting and AC Stark shift in Li/sub 2/ vapor.
