The Cross

The necessary conditions for the correct measurement of the width and angle of divergence of the laser beam are determined taking into account the finite dimensions of the aperture of the emitter by a method based on the determination of initial spatial moments. It is shown that in this case stringent conditions are imposed on the shape of the spatial intensity distribution in the cross section of the laser beam, which were not taken into account in the corresponding developed standards.
