NEW INVESTIGATIONS OF THE PHASE DISTRIBUTION WITH VARIABLE COHERENCE

A. Fougères; J.R. Torgerson; L. Mandel

Abstract New measurement of the probability distribution of the optical phase difference between two light beams have been carried out for different degrees of mutal coherence, when the average number of detected photons is of unity. The measurement time was made much longer than the coherence time. Good agreement with our operational theory for the quantum phase is again obtained.

Effect of varying dye flow velocity on dye laser statistics

Samir Bali; J. W. Noh; A. Fougères; F.C. Cheng; L. Mandel

Abstract With the help of photon coincidence counting measurements we have studied the dependence of the relative intensity fluctuations λ(0)=〈(ΔI)2〉/〈I〉2 on the output light intensity 〈I〉 of a single-mode dye jet laser at two different dye flow velocities. We find that varying the flow velocity causes a rotation and a thickness change of the dye jet. When these effects are compensated, there is no discernible dependence of the dye laser statistics on the flow velocity in the range 12.1 m/s to 13.4 m/s.
