报道了最新一代天文用激光频率梳（LFC）。新的功能包括所有光纤耦合，无干扰滤波腔;专门设计的光子晶体光纤光谱展宽;反射光谱平坦系统。所有这些特性保证了整个LFC系统的长期稳定性。LFC被设计为在两种模式下运行。可见光模式产生从445 nm到870 nm的超连续谱，覆盖了凯克行星望远镜（KPF）光谱仪的100%光谱范围。近红外模式提供了从915 nm到1450 nm的平顶超连续谱，可作为近红外光谱仪短波长部分的定标源
e report a latest generation of the laser frequency comb (LFC) for astronomy. The new features include all fiber coupled, alignment-free filter cavities; specially designed photonic crystal fiber for spectral broadening; reflective spectral flattening systems. All the features ensure the long-term stability of the whole LFC system. The LFC is designed to operate in two modes. The visible mode generates a supercontinuum from 445 nm to 870 nm, that covers 100 % spectral range of the Keck Planet Finder (KPF) spectrograph. The near-infrared mode offers a flat-top supercontinuum from 915 nm to 1450 nm, is prepared as a calibration source of the short-wavelength part of a near infrared (NIR) spectrograph
