Phys. Rev. Lett. 55, 2802–2805 (1985)Correlated Spontaneous-Emission Lasers: Quenching of Quantum Fluctuations in the Relative Phase AngleReceived 26 September 1985; published in the issue dated 16 December 1985 In quantum-beat and Hanle-effect experiments, spontaneous-emission events from two coherently excited states are strongly correlated. A doubly resonant laser cavity driven by such atomic configurations can have vanishing diffusion coefficient for the relative phase angle. © 1985 The American Physical Society URL:
