title: Hybrid booster at 1940 nm based on Tm:Lu₂O₃ ceramics implementing fiber combined signal and pump sources.
abstract: A novel concept of a booster amplifier for a pulsed Tm fiber laser at 1940 nm based on Tm:Lu2O3 ceramics and implementing fiber-combined signal and pump was examined. The pumping emission of the ceramics at 1678 nm was obtained from Raman-shifted Er fiber laser radiation. The hybrid fiber-ceramics amplifier with a gain factor of up to 6 dB and a pulse energy of more than 650 μJ with single-mode output was demonstrated.
