Acousto-Optic Deflector AODF 4055
The AODF 4055 TeO₂ acousto-optic deflector is designed for 0.68–1.30 µm, covering visible red to near-infrared beam control in multiwavelength lasers. TeO₂ operates in an off-axis shear-wave acoustic mode for efficient diffracted-beam deflection. Input polarization is 0° to the mounting plane and output polarization 90°, supporting predictable integration. The RF center frequency is 55 MHz and bandwidth 40 MHz. Antireflection coatings optimized for 0.63–1.06 µm provide low insertion loss with a defined clear aperture. Frequency ranges, beam-separation angles, and RF power are specified separately for 0.68 µm, 0.95 µm, and 1.30 µm to support multiwavelength engineering integration.
