Phys. Rev. Lett. 63, 240–243 (1989)Normal-mode splitting and linewidth averaging for two-state atoms in an optical cavityReceived 3 April 1989; published in the issue dated 17 July 1989 An investigation of the radiative processes for a collection of N two-state atoms strongly coupled to the field of a high-finesse optical cavity is presented. Observations of the spectral response of the composite system to weak external modulation reveal a coupling-induced normal-mode splitting. Linewidth averaging leads to linewidths below the free-space atomic width. © 1989 The American Physical Society URL:
