Abstract

The stretcher with a deformable mirror in its Fourier plane can be used to manipulate the spectral phase. This scheme result in the following result: Ideally, these beams return in parallel lights when they have the same angles of incidence and pass through the deformable mirror. The non-planar structure of the surface result in a change in the direction of the wave vector of the reflected lights, affect the spatial frequency of the pulses and the energy distribution of the final focal spot. In this paper, we report the feasibility study of using a deformable mirror to compensate spectral phase in high-energy petawatt laser facility, simulate its structure and explore the influence of the change of the spatial wave vector introduced. It is found that the changed space wave vector has little effect on far-field focal spot and is positively correlated with the spectral phase amplitude to be compensated.
