According to the design and the principle of the ffner stretcher, the pulse stretcher for OPCPA laser system was experimentally investigated. Using the numerical method, the four key parameters were appropriately selected, that is the angle of incidence being 51.05°, the distance from grating to concave spherical mirror being 653 mm, the curvature radius of the concave spherical mirror being 1 000 mm and the grating constant being 1 800 lines/mm. The experimental results demonstrate that an expansion of 30 fs to 545 ps pulse and a stretching ratio of 18,167 can be obtained by adjusting the key parameters.
