Geometry and energy parameters part of the beam of the laser diode with an extremely diffraction divergence

One of the main signs of degradation of laser diodes (LD) is the change over time of the mode composition of radiation. About the mode composition is judged by the analysis of the radiation pattern (the NAM) radiation in space. That is why in this paper focused attention on research NAM LD emission. At the same time determined by the geometry and energy parameters of the radiation beam LD described by a Gaussian function.
