摘要：

Few -cycle pulses were generated by passing a beam from a cryogenically cooled Fe:ZnSe chirped -pulse amplifier (CPA) at a repetition rate of 400 Hz through a gas -filled hollow core fiber (HCF) followed by dispersion -compensating bulk CaF 2 . The krypton -filled fiber at 370 kPa yielded 1.14-mJ, 42-fs pulses centered at 4.07 mu m, while the oxygen -filled fiber at 310 kPa delivered 0.78-mJ, 39-fs pulses spanning from 3 to 5.5 mu m. This work is a step toward a high repetition rate mid -wave infrared driver of isolated attosecond keV x-ray pulses. (c) 2024 Optica Publishing Group
