We report a novel method to manipulate the direction of a laser beam by controlling the thickness of a dielectric elastomer. The system is controlled by applying different voltages to multi-layers of dielectric elastomers without mechanical movement. We employed laser beams with different wavelengths to test the proposed system, and the experimental results showed that it has an excellent transmittance profile in the ultraviolet and visible wavelength bands, and that we achieved high-precision control in the micrometer range. The results show the feasibility of this technique for laser applications that require high positional accuracy, such as laser cutting, drilling machines, and 3D printing.
