Acousto-optic deflectors

Achieve unmatched precision and speed with G&H's acousto-optic deflectors (AO deflectors), designed for high-speed laser beam scanning across a wide range of applications. With operating rates exceeding 250 MHz, our AO deflectors deliver exceptional performance, making them ideal for material processing, digital imaging, and more.

Incredible Accuracy at Incredible Speeds

Our AO deflectors resolve hundreds to thousands of spots within just a few degrees, enabling scan times as fast as a few microseconds. The total number of resolvable spots is determined by the acoustic wave's traversal time across the optical beam within the AO crystal (known as access time) and the operating frequency bandwidth.

Wavelength Coverage and Scan Angles

Our AO deflectors provide comprehensive wavelength coverage from 266 nm to 10.6 µm, with typical scan angles ranging from ~5 mrad to >60 mrad, depending on the wavelength and RF bandwidth. These capabilities ensure flexibility for diverse laser beam scanning requirements.

Highly Uniform Diffraction Efficiency

Whether performing 1D or 2D beam scanning or deflecting a beam through a fixed angle, our AO deflectors deliver highly uniform diffraction efficiency across the full scan angle. This ensures consistent power throughput, critical for high-precision applications.

Flexible Design Options

We offer a variety of active aperture sizes, up to 15 mm, and utilize high-performance AO materials, including:

  • TeO₂
  • Crystal Quartz
  • Germanium
  • Sapphire

Custom design options are also available, including solutions optimized for shorter wavelengths and wider scan angles to meet the unique needs of volume OEM applications.

Advanced 2D UV Beam Scanning

For advanced 2D UV beam scanning, two UV deflectors can be cascaded in series. Our AODF Dual Driver with phase-synchronized outputs provides optimal RF driver control for these applications, enabling seamless and precise beam manipulation.

Standard and Customized Solutions

We offer a wide range of standard AO deflectors for wavelengths from 266 nm to 1500 nm. For specialized applications, we provide custom AO deflector solutions, including multi-channel configurations for high-speed, high-volume OEM requirements.
