Abstract
A phase-locked frequency comb in the near-infrared is demonstrated with a mode-locked, Erbium-doped, fiber laser, whose output is amplified and spectrally broadened in dispersion-flattened highly nonlinear optical fiber to span from 1100 nm to >2200 nm. The supercontinuum output comprises a frequency comb with a spacing set by the laser repetition rate and an offset set by the carrier-envelope offset frequency, which is detected with the standard f-to-2f heterodyne technique. The comb spacing and offset frequency are phase-locked to a stable rf signal with a fiber stretcher in the laser cavity and by control of the pump laser power, respectively. This infrared comb permits frequency metrology experiments in the near-infrared in a compact, fiber-laser-based system.Citation
