Measurements of absolute optical-frequencies of various stabilized-lasers have been realized by using a femtosecond mode-locked laser and a phonic-crystal optical fiber (produced at the University of Bath, U.K.). The uncertainty of the measurements is 10-11 at present, and can be potentially improved to be better than 10-13. In future, this technology will be applied to the optical frequency syntheses in various fields.
