摘要：

We report a compact and reliable ultrafast fiber laser system optimized for seeding a high energy, 2 mu m pumped, 3 mu m wavelength optical parametric chirped pulse amplification to drive soft X-ray high harmonics. The system delivers 100 MHz narrowband 2 mu m pulses with >1 nJ energy, synchronized with ultra-broadband optical pulses with a similar to 1 mu m FWHM spectrum centered at 3 mu m with 39 pJ pulse energy. The 2 mu m and 3 mu m pulses are derived from a single 1.5 mu m fiber oscillator, fully fiber integrated with free-space downconversion for the 3 mu m. The system operates hands-off with power instabilities <0.2% over extended periods of time. (c) 2024 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
