Abstract: A description is given of a method for measuring the optical inhomogeneity of an active medium at the lasing wavelength. This method is based on the determination of the phase front of the output radiation of a laser. Two variants of the proposed method are tested experimentally. The distributions of the refractive index found in this way are practically identical with the results obtained using other methods.
