Nonlinear optics with atomic mercury vapor inside a hollow-core photonic crystal fiber — •Ulrich Vogl, Christian Peuntinger, Nicolas Y. Joly, Philip St. J.

We demonstrate high atomic mercury vapor pressure in a kagomé-style hollow-core photonic crystal fiber at room temperature. After a few days of exposure to mercury vapor the fiber is homogeneously filled and the optical depth achieved remains constant. With incoherent optical pumping from the ground state we achieve an optical depth of 114 at the 6³P₂ - 6³D₃ transition, corresponding to an atomic mercury number density of 6 × 10¹⁰ cm⁻³ [1]. We present Autler-Townes spectroscopy at low light levels and first results demonstrating all-optical delay of pulses in the system. Currently we investigate soliton dynamics and self-induced transparency phenomena in the mercury-filled fiber system.
