The optical frequency comb, a spectrum of optical radiation composed of evenly spaced and phase-coherent narrow spectral lines, was initially developed for precise time and frequency measurements. Over the past two decades, it has shown broad application prospects in fields such as astronomy, cosmology, optical atomic clocks and quantum key distribution. However, the implementation of magnonic frequency combs for high-precision magnonic frequency measurements remains a challenge.
