On principle, the coherent light intensity in a laser cavity should be calculated according to field strength superposition of the light waves propagating back and forth in the cavity. This paper compares the calculations using the field strength superposition and that using the usual light intensity superposition. Our work indicates that the results on local saturated gain and light intensity calculations really give considerable discrepancies, but the field distribution and power output calculations agree quite well.
