Abstract
An electro-optical modulator (EOM) array that simultaneously modulates a plurality of optical beams. The EOM array has particular application for use in a seed beam source for an SBC fiber laser amplifier system, where the seed beam source includes a plurality of master oscillators each providing an optical seed beam at a different wavelength on a fiber. The EOM array has a common substrate, a plurality of parallel waveguides and an electrode structure, where each waveguide is coupled to one of the fibers to receive one of the seed beams. An RF source provides an RF drive signal to the electrode structure that modulates the seed beams. The fiber laser amplifier system amplifies each of the seed beams from the EOM array, and includes an SBC grating that spatially combines the amplified beams at the different wavelengths so that they are directed in the same direction as an output beam.
