An AO Modulator is a device that modulates and controls the intensity of an optical beam. For highest speeds the laser beam will be focused down, forming a beam waist as it passes through the Modulator. The main factors that dictate the design, and therefore choice of device, are the operating wavelength and the speed. The wavelength and optical power will heavily influence the choice of interaction medium, and the speed will determine the minimum drive frequency, and thus the acoustic transducer design.

 

Gooch & Housego manufactures an extensive range of AO Modulators from a variety of materials covering UV to mid IR for scientific, industrial & biomedical applications. Many of these products are also available Fibre-Coupled and we also offer a comprehensive range of purpose designed RF drivers.

 

We take pride in developing custom-made solutions and ensure that all areas of critial production are carried out in-house, from material selection to fina assembly and test.
