  • In this thesis I describe the generation of a narrow spectroscopic feature using a new technique called 'magnetically-induced optical transparency'' (MIT). A cold ensemble of 88Sr atoms interacts with a single mode of a high-finesse optical cavity via the 7.5 kHz linewidth, spin forbidden 1S0 to 3P1 transition. By applying a magnetic field that shifts two excited state Zeeman levels, a transmission window is opened through the cavity where the collective vacuum Rabi splitting due to a single level would normally create destructive interference for probe transmission.

    The spectroscopic feature approaches the atomic transition linewidth, which is much narrower than the cavity linewidth, and is highly immune to the reference cavity length fluctuations that limit current state-of-the-art laser frequency stability.
