Frequency Combs: A Key Tool in Modern Science
December 29, 2025 – A new article published in today’s e-paper of The Hindu, details the growing importance of “frequency combs” in various scientific applications. These specialized lasers, which emit light across a wide spectrum of evenly spaced frequencies, are revolutionizing how scientists measure and compare light frequencies with incredible precision.
The article explains that frequency combs allow researchers to calibrate atomic clocks, measure shifts in light caused by gravity, and even determine the exact frequencies of light emitted by new lasers. The principle involves comparing an unknown light source to the known, stable frequencies of the comb, allowing scientists to identify the unknown frequency with exceptional accuracy.
The image accompanying the article shows a frequency comb installed on the High Accuracy Radial Velocity Planet Searcher in Chile. The Hindu article emphasizes the fundamental role frequency combs play in advancing research across diverse fields of science. The full article, published under the “Question Corner / physics” section, is available on The Hindu’s website.
