Where to Buy Acousto-optic Modulators

CSRayzer offers acousto-optic modulators with fast modulation speed, low insertion loss, high extinction ratio, low power consumption, good temperature stability and high performance reliability. The possible wavelength regions are from the visible to the infrared. They have an all-metal structure design, compact and sturdy hermetic packaging structure, and innovative packaging technology to ensure high reliability and temperature stability. CSRayzer provides free space or fiber-coupled versions in a wavelength range from 300 nm to 2000 nm, and frequency range from 35 MHz to 300 MHz. They are suitable e.g. for Q-switched fiber lasers, laser Doppler coherent applications, ultrafast laser frequency pulse pickers, and linear frequency adjustment.

SHIPS TODAY: These fiber-coupled acousto-optic modulators (AOM) are designed to offer an optimal solution for amplitude modulation of laser light in a single mode optical fiber. They are offered for wavelengths between 750 nm and 1750 nm with most models stock. These fiber AOMs are easy to use and allow direct control of the timing, intensity, and temporal shape of the laser output down to a few nanoseconds. A fiber-coupled AOM requires an RF driver. AeroDIODE offers a range of RF drivers configured for either digital input (TTL) or analog input configurations. Additionally, the AeroDIODE TOMBAK pulse picker synchronization tool is offered for complex synchronization applications such as pulse-picking a mode locked laser. NEW: a turn-key pulse picker solution is now also offered which combines the synchronization electronics with the high performances AOMs and associated drivers.

DayOptics offers a polarization-maintaining AOM (acousto-optic modulator) which is specially developed for the requirements of optical sensing. It has the advantages of small size, low power consumption, fast rise time, good modulation pulse shape (small overshoot), good pulse repeatability (small repetition period jitter), etc. An integrated package containing both the modulator and the driver facilitates system integration. The device features a high damage threshold and high extincition ratio, and can be widely used in various optical fiber sensing systems that require pulse modulation, such as φ-OTDR, BOTDR, and OFDR.

GWU's assortment of acousto-optical components covers all kind of Q-switches, modulators, deflectors and frequency shifters for various applications. The acousto-optical modulators (AOM) can be configured in flexible design, free-space or fiber-coupled and can be equipped with suitable driving electronics.
