Abstract
Single-channel deformable mirrors for use in low-correction-order laser adaptive systems were developed and investigated. The structure of the mirrors is described and the results are given of experimental determinations of the initial shape of the optical surface, of the response functions, of the sensitivity, and of the electromechanical hysteresis. Calculations are reported of the thermal deformation of the mirrors subjected to the effects of heat under various conditions, and also of the frequency characteristics of these mirrors. It is shown that such adaptive mirrors are effective in compensation for large-scale axisymmetric distortions of the wavefront in laser optics operating at powers up to 1 kW. The operational range of these mirrors is approximately ±20 μm in respect of the amplitude of the optical surface displacements and up to 1 kHz in respect of the frequency.
