The EM4 Fiber Coupled Acousto-Optic Modulator (AOM) product range comprises a series of rugged, hermetic modules that have been designed and built using technologies and processes developed for high reliability defense and telecommunications applications. Modules are pigtailed with polarization maintaining fiber on the input and output as required and contain internal circuitry for 50Ω RF matching.

In addition to  fiber coupled modules, we also provide a range of compatible drivers, making it quick and easy to integrate fiber coupled AOM's into larger systems.

With the fastest AOM module and driver combination providing rise/fall times <10ns, they can be used as pulse pickers in high repetition rate femto-second fiber lasers and other demanding switching applications.
