Abstract
A system for producing frequency converted light includes a first seed laser operable to provide a first laser signal and a second seed laser operable to provide a second laser signal. The system also includes an optical combiner optically coupled to the first seed laser and the second seed laser. The optical combiner is operative to combine the first laser signal and the second laser signal into a combined laser signal. The system further includes a power amplifier optically coupled to the optical combiner. An intensity of both the first laser signal and the second laser signal are increased by the power amplifier. The system additionally includes a harmonic converter optically coupled to the power amplifier.
