Abstract
We report a practical experimental implementation of time-resolved optical gating (TROG) using a dispersive pulse (DP) propagation geometry and a two-photon absorption nonlinear detector. A measurement of 50 fs pulses from a self-mode-locked Ti:sapphire laser is demonstrated and a general procedure for calibrating the dispersion axis of the TROG trace is presented. A complete iterative pulse retrieval algorithm is described and the limitations of the DP-TROG technique are discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
