Abstract: The method of wavefront doubled-frequency spherical modulation for determining the laser beam waist position has been simulated and experimentally studied. The error in determining the focal plane position is less than 10^-5 D. The amplitude of the control doubled-frequency electric signal is experimentally found to correspond to 12% of the total radiation power.

Keywords: laser beam, focusing, adaptive optics, wavefront doubledfrequency spherical probing.
