| Abstract: | Time resolved spectral interferometry is applied to femtosecond pulse coherent measurement. A new configuration that can be directly applied to single shot detection is presented. The efficiency of this self-referenced real-time passive technique is experimentally demonstrated during the characterization of chirped pulses. Additionally, we quantitatively retrieve the spectral phase shift which is associated to the propagation through a F4 glass parallel plate. Numerical results are also reported showing examples of complex pulse characterization. Finally, limitations of the technique are discussed. |
