Optical Frequency Comb 〈2025-2026〉

: Most combs are created using mode-locked lasers that produce a train of ultra-short pulses at regular intervals. The Comb Equation : Every individual frequency in the comb ( νnnu sub n ) is defined by just two parameters:

: Generated by modulating a continuous laser with radio waves, allowing for highly tunable tooth spacing. Optical Frequency Combs | NIST optical frequency comb

: Modern miniaturized versions small enough to fit on a microchip, opening doors for use in smartphones or portable medical devices. : Most combs are created using mode-locked lasers
