Abstract

To ensure high contrast ratio for the SHENGUANG (SG) II petawatt upgrade laser facility, many factors such as pulse spectral clipping, chromatic aberration and manufacture errors of the optical elements are considered carefully in the design of the pulse stretcher. An eight pass Öffner configuration is selected for the laser system and the final design of the stretcher is also given out.
