Gooch & Housego, Florida LLC's AO Modulator (AOM) Product line:

15000 / 17000 Series:
The 15000 / 17000 series of Acousto-Optic Modulator Systems consists of High Speed AO Modulators and RF Drivers ideal for use in high speed shuttering applications or optical pulse generators. These systems use high efficiency, anti-reflection coated, TeO2 crystals.
An optional 71000 series assembly is available, consisting of AR coated input / output coupling optics mounted in an integral precision alignment assembly, for optimum focusing of the input laser beam and collimation of the deflected output beam. The combination of high RF carrier frequency and optimum lens design results in a large angular separation, of up to 65 milliradians, between the zero and the first order deflected output beams. This makes it easy to separate the two beams in space and maintain a static contrast ratio of at least 500:1.

23000 series:
The 23000 series of Acousto-Optic Modulator is made from TeO2 crystals. Because of its high figure of merit, the required drive power is low, usually less than a Watt, and can still accept high input optical power in the visible and near-IR range.

24000 series:
The 24000 series of Acousto-Optic Modulator is made from flint glass. This AO material has a lower figure of merit than TeO2, but its cost is significantly less. This series is use in applications with bandwidths of less than 1 MHz and moderate power, light density. it is an inexpensive alternative to other materials.

26000 series:
The 26000 series of Acousto-Optic Modulator is made from AMTIR (GeSeAs). These AO Modulators are for use at 1.3, 1.5 or 1.59 μm wavelength and comes with or without FO fiber input coupling. This series can be used in digital switching, analog modulation, or frequency shifting applications.

35000 Series:
The 35000 Series of Acousto-Optic Modulator is made from Crystal Quartz, Fused Silica, or KrF Grade Fused Silica. These AO Modulators are for use with high power Argon Ion lasers (up to 20 Watts) and are coated typically for, either 300 to 400 nm, or 440 to 540 nm spectral regions. These modulators can be coated for wavelengths from 244 nm up to 700 nm.

37000 Series:
The 37000 Series of Acousto-Optic Modulator is made from Germanium. These devices are for use in the spectral range of 2.5 to 15 μm. These Modulators are AR coated for 10.6 μm as standard or can custom AR coated for the "customer specified" wavelength.
