Efficient second-harmonic generation at 384 nm in periodically poled lithium tantalate by use of a visible Yb–Er-seeded fiber source

Abstract

We generated 56 mW of average power at 384 nm in periodically poled lithium tantalate by use of a visible fiber source based on a variable-pulse format seeded Yb–Er amplifier and frequency upconversion in periodically poled KTP. The feasibility of high-average-power, wide ultraviolet wavelength–range fiber-based sources is evaluated.
