After evacuation, overall efficiency exceeded 70%, the output was a near-diffraction-limited Gaussian spot, and the fundamental-mode energy fraction exceeded 95%.

    Why we recommend it: The paper gives efficiency, pulse duration, peak power and fundamental-mode fraction, and compares the fiber with free-space optics and solid-core fluoride fiber, making it easier to judge the applicability of hollow-core fiber to mid-infrared ultrafast delivery.
