Popis: An optimal stretcher-compressor scheme is designed for laser facilities based onbased on optical parametric chirped-pulse amplification under picosecond (∼100 ps) pumping, which enables one to attain petawatt peak power of pulses less than 10 fs with high contrast and low aberrations. The stretcher design is based on an Ofner telescope with spherical mirrors and two diffraction gratings, one being placed at the center of the spherical mirrors. It is shown to be the only possible aberration-free stretcher design. The simulation performed has shown that a compressor consisting of four transmission diffraction gratings with an aperture 112 × 125 mm, a thickness of 3 mm, and chirped mirrors with 100-mm aperture that introduce −4500 fs2 dispersion allows amplified pulse compression down to
