Influence of Atomic Phase Fluctuations on Field Squeezing and Brightness of Many Two-Photon Correlat ed-Spont aneous-Emission Lasers

We show in this paper that phase fluctuations of active atoms in many twephoton correlatedspontaneous-emission lasers will reduce field squeezings and brightness of the squeezed light. But, under certain conditions of laser operation, the fluctuations of atomic phases between lower almost degenerate atomic levels could increase the squeezings and the brightness. We also show that, even for large phase fluctuations of the active atoms, almost perfect field squeezings and substantial brightness of the squeezed light can be obtained.
