title: Electromagnetically induced Bragg reflection with a stationary coupling field in a buffer rubidium vapor cell.
abstract: An electromagnetically induced Bragg reflection with a stationary coupling field in an Rb vapor cell with a 6.67 kPa neon buffer gas was studied. When the coupling field was spatially modulated as a stationary wave, a transmission reduction of the probe field was observed, while simultaneously a reflected probe field was detected in the backward direction. Instead of absorbing a fraction of the probe laser in the Rb vapor, the modulated electromagnetically induced transparency medium reflected it, corresponding to a Bragg reflection. The spectrum in the 5S(1/2)-5P(1/2)Lambda-type system of (87)Rb atoms was investigated as a function of the coupling laser frequency detuning, the stationary coupling laser power, the vapor cell temperature, and the coupling laser power ratio.
