Abstract:

The problem of formation of a light beam wave front with flexible or segmented mirrors is considered. A detailed analysis of the influence of the beam intensity profile as well as of the ratio of an actuator range to a beam radius on the quality of the beam focusing is given. Some feasible approaches to modeling of the focusing procedure when using a segmented mirror are discussed. Certain differences between the results obtained using the present field approximation and those obtained using numerical simulations on inversion of the wave front in the case of four-wave interaction under conditions of strong energy exchange between the waves and their self-action are pointed out.
