We report on the investigation of a novel ceramic Tm:Lu2O3 amplifier lasing at around 2-μm and offering efficient generation of high-energy pulses with high-peak power at high repletion rate, high efficiency, and with near-diffraction-limited beam quality (BQ). The amplifier has a bandwidth of over 300 nm, which offers broad tunability. The bandwidth also supports generation of ultrashort pulses in the femtosecond regime. The “2-for-1” pump architecture of the Tm ion enables high optical-to-optical efficiency while pumping at around 800 nm. High thermal conductivity of the Lu2O3 host supports operation at high-average power. The ceramic nature of the Lu2O3 host overcomes the scalability limits of single crystal sesquioxides.
