摘要

据我们所知，我们报告了第一种高效的基于Yb: luag的Innoslab放大器，在175 kHz时，脉冲能量为1.37 mJ，平均输出功率为242 W，通过光栅压缩机可压缩至360 fs。该系统的光效率为40.7%，功率稳定性良好，均方根波动仅为0.11%。值得注意的是，这种紧凑的单级放大器结构从1 W注入种子产生191 W的放大输出功率，同时在最大输出时保持优异的光束质量（M2 < 1.5）。

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 (M² < 1.5) at the maximum output.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
