Abstract

Monomode laser sources with fast frequency chirping capabilities are crucial in several fields, including optical processing of RF signals [1], reflectometry or coherent manipulation of atoms. All these domains need fast and mode- hop-free frequency scans through a broad spectral range (typically 10 GHz in 1 ms) with high spectral purity. It means that the frequency deviation from a perfect linear chirp has to be much lower than 1 MHz when integrated over the whole chirp bandwidth.
