Abstract
A method of generating frequency combs composed of a predetermined number of rays, wherein the method includes the modulation of a main ray generated by a laser source (20), by a first radiofrequency signal at a first frequency value, by a second radio frequency signal at a second frequency value, and by a third radio frequency signal at a third frequency value. The second frequency value is equal to twice the first frequency value. The third frequency value is equal to three times the first frequency value.
