Abstract

A frequency comb is generated with a chromium-doped forsterite femtosecond laser, spectrally broadened in dispersion-shifted highly nonlinear fiber, and stabilized. The resultant evenly spaced comb of frequencies ranges from 1.1 to beyond 1.8 υm. The frequency comb was referenced simultaneously to the National Institute of Standards and Technology's optical frequency standard based on neutral calcium and to a hydrogen maser that is calibrated by a cesium atomic fountain clock. With this comb, we measured two frequency references in the telecommunications band: one half the frequency of the d/f crossover transition in 87Rb at 780 nm, and the methane Ņ2 + 2Ņ3 R(8) line at 1315 nm.
