High-Speed Acousto-Optic Modulators
Description
The High-Speed Acousto-Optic Modulators (AOM) from CASTECH offer cutting-edge technology for precise laser intensity modulation. Designed for extracavity use, these modulators are ideal for applications requiring rapid and accurate control of laser beam intensity. With rise/fall times as low as 6 ns and a frequency range extending up to 300 MHz, these AOMs deliver exceptional performance for a variety of demanding applications.
The modulators utilize acoustic waves to modulate the intensity of the laser beam, and they are compatible with both digital (on/off) and analog (sine, square wave, linear, random) RF drivers. This flexibility allows for a range of modulation modes to meet specific application needs. The performance of the AOM is closely related to the beam diameter; thus, precise control of the laser beam is necessary to achieve optimal modulation speeds.
CASTECH offers customization options for modulation speed, wavelength, power, beam diameter, and extinction ratio, ensuring that each modulator can be tailored to meet the unique requirements of different applications. From laser marking to medical procedures, these modulators provide reliable and high-quality solutions, backed by CASTECH’s commitment to precision engineering and high manufacturing standards.

Frequently Asked Questions
An Acousto-Optic Modulator (AOM) is a device used to control the intensity of a laser beam through the use of acoustic waves. It modulates the laser's amplitude by creating varying refractive indices within the optical medium, which affects the laser beam's intensity.
These AOMs are compatible with both digital RF drivers (on/off) and analog RF drivers, which include sine, square wave, linear, and random waveforms.
The performance of an AOM, particularly the rise/fall time, is influenced by the diameter of the incident laser beam. To achieve optimal modulation speeds and performance, precise control of the beam diameter is necessary.
Yes, CASTECH offers customization options for these AOMs. You can tailor parameters such as modulation speed, wavelength, power, beam diameter, and extinction ratio to meet specific application requirements.
The rise/fall time of an AOM is crucial as it determines the speed at which the modulator can change the intensity of the laser beam. Faster rise/fall times enable more rapid and precise modulation, which is essential for high-speed and high-accuracy applications.
When selecting an AOM, consider factors such as the required modulation speed, wavelength, power, beam diameter, and extinction ratio. CASTECH can assist in customizing the AOM to meet your specific needs based on these parameters.
The lifespan of a High-Speed AOM depends on its operating conditions and usage. CASTECH products are designed for high durability and reliability, but proper handling and maintenance are essential for maximizing their operational lifespan.
