Abstract :
Summary form only given. Here we demonstrate an extension of the dispersion sensitive method that combines its phase sensitivity with comb mode resolution, pushing its resolution limitations down to laser line width. The basic idea is to detune the resonator with respect to the driving frequency comb such that the cavity mode frequency spacing is and integer fraction like 10/9th of the frequency comb repetition frequency.
