Abstract

The possibility to control an intensity distribution in the far field of a powerful laser system by high-frequency moving the position of a focal spot is considered. Quadruple electro-optic deflector (beam wiggler) on the base of LiNbO₃ crystal installed in resonance cavity has been developed and constructed. The main parameters of the device are as follows: amplitude of the angular deflection plus or minus 4 dif.limit, clear aperture 1 cm, the deflector is designed for operation at 6.5 GHz powerful microwave source. Results of beam wiggler dynamic testing are presented and discussed.
