Frequency Comb Lasers Enable Clearer Observation of Black Holes
A research team led by KAIST professor Jungwon Kim has integrated optical frequency‑comb lasers into radio‑telescope receivers, achieving the world’s first laser‑based reference signal for Very Long Baseline Interferometry (VLBI). The ultra‑precise comb provides thousands of stable frequencies, allowing exact phase alignment across multiple telescopes and eliminating the vibration‑induced errors of traditional electronic references. Test observations on Korea’s VLBI Network confirmed stable interference fringes and clearer imaging of black holes, and the system is now being deployed at additional sites. The breakthrough promises to improve black‑hole imaging, ultra‑precise time transfer, space geodesy, and deep‑space navigation.
