dc.description.abstract	The task of this work is development of precision chaotic laser generation principles. Its implementation will contribute to evolution of telecommunication systems based on the chaotic generators synchronization effect and other chaotic technology. The key problem for practical use of chaotic regimes is their strong dependence on fluctuations of initial conditions and weak external influences. This is a fundamental property of dynamic chaos. To solve the stated problem, we analyze the semiclassical laser equations for the stable, unstable, and chaotic generation modes. A modified equation for chaotic radiation is obtained. It is supplemented with fluctuations of the pumping parameters, laser components characteristics, and external factors. The equation is the basis for studying of laser dynamics under various initial conditions and for providing of precision chaotic generation.We propose a definition for precision chaotic laser generation. It is the generation of laser radiation, the dynamics of which is classified as chaotic with a given accuracy and is reproducible within the boundaries of the phase portrait. The choice of the phase portrait. as the object of study for precision, is due to the stability of chaotic solutions according to Lagrange. The precision is confirmed by comparing a phase portrait of the system with its reference portrait, obtained with controlled reference parameters of chaotic radiation. As the quantitative estimates of chaotic precision are chosen: the volume of attractor, Lyapunov exponents, and Hurst coefficient with allowable deviations. The precision of chaotic generation and control of chaotic dynamics are ensured by the precision of the pump parameters, by control and stabilization of the components and characteristics of laser, such as the size and dynamics of resonator, quality factor, radiation frequency, temperature, and others.
