| contents | Chirped-pulse interferometry (CPI) is a classical low-coherence interferometry technique with automatic dispersion cancellation and improved resolution over white-light interference. Previous work has shown that CPI with linearly-chirped Gaussian laser pulses achieves a $\sqrt{2}$ improvement in resolution over conventional white-light interferometry, but this is less than the factor of 2 improvement exhibited by a comparable quantum technique. In this work, we show how a particular class of nonlinearly-chirped laser pulses can meet, and even exceed, the factor of 2 improvement resolution. This enhanced resolution CPI removes the remaining advantage of quantum interferometers in dispersion-cancelled interferometry. |
