| 摘 要： | A cylindrical ?ffner stretcher based on ternary reflector(COSTER) is proposed and analyzed. Compared with the traditional?ffner stretcher, the COSTER has no off-axis aberration in the multipass configuration, and the output laser of COSTER has lower spectral phase noise and higher temporal contrast in the far field. The COSTER is quite suitable to be used in multipetawatt laser facilities, and it might be the preferred stretcher configuration for ultrafast and ultra-intense lasers.
