Abstract

It is shown that the negative nonlinearity of the refractive index leads to the selection of the optimal self-defocusing scales and the optimal (nonlinear) coherence radius of laser radiation pulses. This ensures the minimal beam divergence and creates a granular fluctuating structure of the radiation with the maximum radiation brightness. The results are compared with the available experimental data for laser radiation pulses in liquids and gases.
