Abstract

We present a phase reconstruction algorithm for a self referenced spectrographic pulse characterization technique called very advanced method for phase and intensity retrieval of e-fields (VAMPIRE). This technique permits a spectral phase reconstruction of pulses with separated frequency components. The algorithm uses the particular characteristics of VAMPIRE spectrograms. It is a locally structured algorithm which is fast, robust, and it allows us to master stagnation problems. The algorithm is tested by use of both simulated and measured data (C) 2014 Elsevier B.V.
