The ThorLabs YDFA100P is a core-pumped ytterbium-doped fiber amplifier delivering high gain and saturated output power across the 1030–1070 nm band. Polarization-maintaining architecture with >20 dB extinction ratio preserves signal polarization state, essential for coherent systems and precision applications. Built-in input and output isolators optimize performance in the 1040–1060 nm window.
