Free-Space Acousto-Optic Modulator (Conduction-Cooled)
This LBTEK acousto-optic modulator operates via Bragg diffraction. It can be used as an optical switch (cyclically switching light on and off at a set frequency) or as a variable attenuator (dynamically controlling transmitted light intensity).
Compatible with multiple operating wavelengths (355-852 nm options available). The conduction-cooled design enables stable operation in continuous-wave (CW) and pulsed laser applications including laser printing, marking, material processing, medical surgery, and microfabrication.
Key Features
- Based on Bragg diffraction with first-order diffracted light separation
- High diffraction efficiency (typically >80% at center frequency)
- Configurable for use as optical switch or variable attenuator
- Matched RF driver and power supply available separately
- Custom configurations available — contact our engineering team
Typical Applications
- Laser marking and engraving
- Material processing and microfabrication
- Medical and surgical laser systems
- Ultrafast fiber laser pulse picking
- Q-switching and seed-source modulation
- Laser cooling and atomic physics experiments
- Frequency stabilization
Product Family
LBTEK's acousto-optic modulator (AOM) series products are based on the principle of acousto-optic interaction, enabling frequency shifting and amplitude modulation of laser light. They can be used as optical switches (cyclically switching light on and off at a set frequency) or as variable attenuators (dynamically controlling the intensity of transmitted light).
