Detuned Single Mode Laser and Detailed Balance

TLDR: The statistical properties of laser light have been investigated both theoretically (e.g. as mentioned in this paper ) and experimentally in great detail, and the theory is rather simple and it agrees with experiments very well.

Abstract: The statistical properties of laser light have been investigated both theoretically (e.g. [1–20]) and experimentally (e.g. [21–30]) in great detail. For a single mode laser not too far from threshold the theory is rather simple (it is essentially governed by only one parameter) and it agrees with experiments very well. In the experiments [21–30] only the statistical properties of the intensity are compared with the theory. Measurements giving information on the statistical properties of the phase of the light field, for instance the usual linewidth, have been made in the threshold region only quite recently [31], see fig. 1.
