Abstract:

Based on the recording and readout structures of femtosecond spectral holography, the entire physical procedures is depicted, and the mathematical expressions for the output pulse field distribution in different directions is given. The choices of the angles of signal, reference and test pulses, and distributions of the signal, reference and test pulses on the spectral plane are discussed. Then the influence of signal, reference and test pulses’ duration on the output pulses is discussed. The results are useful to the ultrashort pulse signal processing including shaping, storage and reconstruction.
