Abstract

The fast steering mirror introduced in this paper using Giant Magnetostrictive Material (GMM) as the offset-generating component, the FSM was actuated by the elasticity of the GMM, which was controlled by the magnetic field generated by the current in the coil around the GMM. This fast steering mirror was applied in the tilt correction system for atmospheric laser beam propagation, and the tilt introduced by the turbulent current was reduced by 90%, the stability and concentration of the laser facula was enhanced greatly.
