Efficient high-power Yb:LuAG Innoslab ultrafast amplifier compressible to 360 fs
We report on the first, to the best of our knowledge, high-efficiency Yb:LuAG-based Innoslab amplifier delivering 242 W average output power with a pulse energy of 1.37 mJ at 175 kHz, compressible down to 360 fs via a grating compressor. The system achieves an optical efficiency of 40.7% and exhibits remarkable power stability with an RMS fluctuation of only 0.11%. Notably, this compact, single-stage amplifier architecture generates 191 W of amplified output power from a 1-W injection seed while maintaining excellent beam quality (M<sup>2</sup> < 1.5) at the maximum output.
