G&H offers a wide variety of multi-channel modulators and can design solutions to fit your needs. As opposed to a typical modulator with just one RF connection to adjust the laser intensity of a single beam, multi-channel acousto-optic modulators have a linear array of independently controlled channels propagating through the same acousto-optic material. Such devices can be used to modulate sections within a sheet of light or individual beams propagating through each of the channels. Applications include high speed micromachining and direct-write-lithography.
Our designs cover an extensive range of wavelengths from UV to the Near IR with channel counts as high as 48. Multi-channel modulators are typically designed and tailored for specific applications. Some previously manufactured models are shown in the table below as representatives for our capabilities.
