Mode Coupling and Detuning in a Ring Laser.

摘要

It is shown that the mode coupling constant for a ring laser is not arbitrary but, to a first approximation, is completely determined by the detuning of the laser cavity from the line center. In the limit far above threshold, it becomes equal to the negative of the intensity cross-correlation coefficient, and its functional dependence on detuning should therefore be demonstrable by photoelectric correlation measurements.
