Abstract
In a frequency-tripled fiber-MOPA, a pre-amplified plane-polarized seed-pulse having a fundamental frequency is divided into two pulse-components, plane-polarized in polarization-orientations at 90-degrees to each other. The fundamental-wavelength pulse-components are amplified in a common amplifier-fiber. The amplified components are separately propagated on different optical paths. One of the amplified components is frequency-doubled. The frequency-doubled component on one path and fundamental-frequency component on the other path are then combined on a common-path and sum-frequency mixed to provide a frequency-tripled pulse.
