A compact kHz-repetition-rate 2-mJ sub-200-fs cw-pumped Yb,Na:CaF2 amplifier

A compact kHz-repetition-rate 2-mJ sub-200-fs cw-pumped Yb,Na:CaF2 amplifier

Using a novel broadband Yb-doped crystal close-loop cooled at -130degC we demonstrate a 2-6-W multi-kilohertz amplifier delivering sub-200-fs pulses with energies up to 2 mJ. This technology is straightforwardly scalable toward a kHz-repetition-rate multi-mJ output.
