Herein, a deformable lens that can directly generate tunable Airy beams was proposed. Compared with other methods, this deformable lens can be embedded in the optical path to directly generate Airy beams. A prototype deformable lens was fabricated, and an optics system based on the wavefront sensor was established to generate Airy beams. Using the fabricated deformable lens, high-quality Airy beams with an adjustable cubic phase were generated. The residual error of generated cubic phase was less than 3.4% of the corresponding target amplitude. The intensity distribution and propagation properties of the generated Airy beams were consistent with the theoretical findings, thereby demonstrating the potential application of the deformable lens in directly generating tunable Airy beams.
