Abstract
The chirp of an ultrashort laser pulse can be extracted accurately in real-time using a simple modified autointerferometric correlation (MOSAIC) technique. Our newly developed time-domain algorithm is well suited for low signal-to-noise conditions. We display results revealing high sensitivity to chirp with signal-to-noise levels approaching the noise floor. Correction algorithms have been developed to accommodate signal distortions arising from bandwidth limitations, interferometer misalignment, and non-quadratic detector response.
