Acousto-optic multi-channel modulators (AOMC) allow multiple beams to be modulated or deflected independently by integrating an array of transducers with a single acousto-optic crystal. The AO multi-channel modulators manufactured by Gooch & Housego (G&H) feature reliable operation and high performance with minimized crosstalk thanks to proprietary optical and electrical designs to allow concurrent operation of up to 48 channels for modulation, and up to 8 channels for beam deflection.

Multi-channel modulators are most often used for high speed applications like micromachining and direct-write lithography, as each beam can be modulated independently. They are also used to increase throughput when writing large media by writing multiple beams at the same time. A typical multi-channel modulator has parallel beams as input, each operated on by a different transducer to modulate its intensity. Available models have 2 to 48 channels for UV through NIR wavelengths, with rise times as short as 7 ns for apertures < 1 mm. Multi-channel RF drivers are available with analog or digital modulation.

High laser damage threshold is achieved using low-scatter materials inspected to rigorous quality standards. We draw our own tellurium oxide (TeO2) and source high quality fused silica and crystalline quartz to ensure low insertion loss and excellent optical power handling.
