We have demonstrated a statistical measurement technique to characterize the mode partition in injection lasers. In the steady state small nonlasing side modes have distributions similar to that of a narrow-band Gaussian noise. There is a certain probability that they carry a significant portion of the total output. For example, if a side mode of a TJS (AlGa)As laser contains on the average 1.6 percent of the total output power, there is a probability of 10-6, that it carries 30 percent of the total output. Distributions of main modes of a multimode laser can be matched by beta distributions with properly selected parameters. In addition to dc conditions, this technique has also been used to study the transient behavior of injection lasers. The dominant mode has been shown to start from a noise distribution.
