IntraAction AOD-70 Acousto-Optic Deflector
An Acousto-optic device designed to deflect or modulate a 633 nm laser beam by 6.5 mrad. Centre frequency 70 MHz, deflection bandwidth 40 MHz.
- Laser beam deflection
- Intensity modulation
- Multiple beam generation
- Flat optical scan response
- Acoustic phased array design1
- Optical signal processing
- Optical frequency shifting
- High reliability
1These deflectors incorporate and acoustic phased-array beam steering design to produce a relatively flat firstorder diffraction efficiency across the deflection bandwidth. Because of this design feature, the deflectors requirea single RF power amplifier to drive the multiple transducer array.
