A frequency comb is generated with a Cr:forsterite femtosecond laser, spectrally broadened through a highly nonlinear optical fiber to span from 1.0 υm to 2.2 υm, and stabilized using the f-to-2f self-referencing technique. The repetition rate and the carrier-envelope offset frequency are stabilized to a hydrogen maser, calibrated by a cesium atomic fountain clock. Simultaneous frequency measurement of a 657 nm CW laser using the stabilized frequency combs from this Cr:forsterite system and a Ti:sapphire laser are in good agreement. The frequency noise of the comb components is observed at 1064 nm, 1314 nm, and 1550 nm by comparing the measured beat frequencies between CW lasers and the Cr:forsterite frequency combs.
