When it comes to acoustic optical devices, we’ve spent years honing our skills in design and manufacturing—making us a reliable choice for anyone needing these tools. Our strong research and manufacturing teams don’t just build products; they ensure each one performs well and meets what customers actually need.
From start to finish, we handle every step of creating core materials. This includes growing, processing, and coating crystal materials like TeO2 and quartz. We also know how to balance different product properties—even when some parameters affect each other—to deliver solutions that fit better. Plus, we keep tight control over key specs like AOM loss, on/off extinction ratio, and rise time, whether you’re looking for standard products or something made just for you.

What Is a Fiber Optic Acousto-Optic Modulator (AOM)?

A Fiber Optic Acousto-optic Modulator (AOM) works on the acousto-optic effect, and it’s pretty versatile: it can adjust a light beam’s frequency, intensity, pulses, and direction. It works with light ranging from visible wavelengths to infrared, so it fits many uses.
For frequency, you can pick from 40–400 MHz, but we also offer custom frequencies if you need something specific. Some models even handle high-power optical inputs up to 5W (we can customize this too) for tougher scenarios. And with an all-metal design, compact and sturdy packaging, and smart packaging tech, these AOMs are reliable and stay stable even when temperatures change.

What Is an Acousto-Optic Frequency Shifter (AOFS)?

If you need to change light’s frequency, an Acousto-optic Frequency Shifter (AOFS) is the tool for it. Here’s how it works: sound waves create a “diffraction grating,” and when light scatters off this grating, it gets a Doppler shift (a change in frequency).
  • If light and sound waves move in the same direction, the diffracted light’s frequency goes up.
  • If they move in opposite directions, the frequency goes down.
The amount of frequency change depends on the output frequency of the AOFS’s RF driver. You’ll often find AOFS used in interference-based optical systems—think optical heterodyne detection, laser Doppler velocity measurement, and laser Doppler vibration measurement.

Our Fiber AOM Series: Options for Every Need

We offer a wide range of fiber AOMs to match different wavelength requirements and uses. Here are some key series you might find useful:
  • 461nm Fiber AOM Series: Uses acousto-optic interaction to modulate laser intensity and shift its frequency.
  • 532nm Fiber AOM Series: Leverages the same acousto-optic principle to adjust laser intensity and frequency.
  • 780nm Fiber AOM Series: Designed specifically to modulate laser beam intensity and shift frequency via acousto-optic interaction.
  • 1064nm Fiber AOM Series: Includes both standard models (based on the acousto-optic effect) and an 1064nm Integrative Fiber AOM Series (combines AOM and driver for higher integration, smaller size, and better frequency stability). There’s also a high-power version for demanding applications.
  • 1550nm Fiber AOM Series: Covers standard, integrative (AOM + driver), and high-power models—all using acousto-optic interaction to modify laser intensity and frequency.
  • 1650nm & 2000nm Fiber AOM Series: Utilize the acousto-optic effect to manipulate laser light, adjusting both intensity and frequency.
  • Customized Fiber AOM: If none of our standard models fit, we can create a custom optical modulator to adjust your laser’s amplitude and frequency.
