Abstract :
Monomode laser sources with fast frequency chirping capabilities are crucial in several fields, including optical processing of RF signals (Gorju, et. al., 2005), 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.
