Abstract

The design, test and optimization of a picosecond CO₂ pulse-forming system are presented. The system switches a semiconductor's optical characteristics at 10 micrometers under the control of a synchronized 1.06-micrometers Nd:YAG picosecond laser pulse. An energy-efficient version of such a system using collimated beams is described. A simple, semi-empirical approach is used to simulate the switching process, specifically including the spatial distributions of the laser energy and phase, which are relevant for experiments in laser-driven electron acceleration.
