The objective of the proposed method is a better knowledge of the spatial energy distribution (SED) supplied by multimodal cavities. The principle of the method consists of observing the laser beam intensity at different locations of a section. After recording the beam with a CCD camera, the information is treated in view to recompose the sources SED. The knowledge of the latter and the fundamental equations allows calculation of the propagation characteristics. The results obtained were compared with those from Badawi's method, and a good agreement was found. The authors concluded the method was valid and decided to continue. The SED after transmission by a step index fiber, is recording and confirmation of the literature results are obtained.
