Acousto-Optic Modulators (AOMs) for Precision Laser Modulation

CASTECH's acousto-optic modulators (AOMs) provide high-speed, extracavity intensity modulation for lasers, enabling accurate control of laser amplitude outside the laser cavity. Designed to operate with a fixed-frequency RF driver (digital or analog), these modulators offer precise modulation capabilities for a wide range of industrial applications. Key features include:

  • Fast Rise/Fall Time: Achieving a rise/fall time as low as 6 ns, ensuring high modulation bandwidth and fast response.
  • Customizable Performance: Design flexibility for modulation speed, wavelength, power, beam diameter, and extinction ratio to meet specific customer requirements.
  • Frequency Range: Capable of operating at frequencies up to 300 MHz, offering versatile performance across different applications.
  • Beam Diameter Sensitivity: Optimal rise/fall times require precise control over the incident laser beam diameter, making the system adaptable to varying application needs.

Applications:

  • Laser Marking: High precision for marking applications in industrial and manufacturing settings.
  • Photolithography: Ideal for controlled light exposure in semiconductor and microelectronics production.
  • Medical Procedures: Offers precise modulation for medical laser systems.
  • Material Processing: Optimized for laser machining, cutting, and engraving processes.

CASTECH’s AOMs are the ideal choice for professionals looking to enhance their laser modulation systems, offering both speed and precision in a variety of applications.
