The selection rules for spontaneous coherent waves in mesoscopic systems are experimentally studied using the transverse patterns of a microcavity laser and theoretically analyzed using the theory of SU(2) coherent states. Comparison of the experimental results with the theoretical analyses reveals that an amplitude factor A should be included in the representation of the partially coherent states. The determination of the amplitude factor A is found to be associated with the constraint of minimum energy uncertainty.
