Browsing: Frequency Comb

A frequency comb is a precise tool used in scientific research, particularly in spectroscopy, metrology, and laser technology, consisting of a spectrum of light that contains many equally spaced, discrete, and coherent frequencies. These combs are typically generated using mode-locked lasers, which produce pulses of light at regular intervals, resulting in a series of sharp spectral lines (the “teeth” of the comb) spaced at regular frequency intervals. Frequency combs are crucial for their role in measuring the frequency of light with extraordinary accuracy and resolution. They have transformative applications, including improving the precision of atomic clocks, enhancing the capabilities of telescopes in detecting exoplanets, and advancing quantum computing technologies. Their development was so significant that part of the 2005 Nobel Prize in Physics was awarded for work related to the optical frequency comb technique.
