Abstract

Laser beam propagated through surface layers of the atmosphere changes its properties under influence of the turbulence effect. To mitigate the consequences of its adaptive optics tools are widely used. In this paper the optimization of main parameters (stroke, first resonance frequency, substrate and piezoplate layers thicknesses) of the bimorph wavefront corrector was performed considering severe atmospheric conditions (refractive index structure constant C_n²=10^-13 m^-2/3, length of the trace L = 500 mm, beam diameter D = 300 mm, wavelength λ = 1064 nm, Fried parameter r_o = 34 mm, wind velocity v = 10 m/s).
