In this paper, the temporal aberrations induced by the different kinds of misalignments of the gratings were discussed and the importance of spatially transverse effects was emphasized. And the basic principles of self-compensation and a set-up based on symmetry considerations were presented.Abstract:
Sensitivity of alignment is one of the major issues in the stretcher-compressor devices used for chirped pulse amplification. In this paper we discuss the temporal aberrations induced by the different kinds of misalignments of the gratings and we emphasize the importance of spatially transverse effects. We discuss simple criteria for minimizing these faults. Finally, we introduce the basic principles of self-compensation and present such a set-up based on symmetry considerations. >read more
