Design of dispersive mirrors for ultrafast applications

Abstract

Different approaches to the design of dispersive mirrors (DMs) for ultrafast applications are considered. High efficiency and good quality of solutions are achieved due to a completely analytical approach to the computations of all DM characteristics and a modern version of the needle optimization technique. Different means to suppress group delay dispersion (GDD) oscillations are demonstrated. Alternatively, design approaches not based on GDD optimization are described, including time-domain design approaches based on direct optimization of pulse energy concentration. © 2010 Chinese Optics Letters.
