In this paper, a femtosecond pulse stretcher based on spherical Offner and cylindrical Offner configuration and stretching factor of 4560 for Ti-Sapphire with central wavelength of 800 nm and 30 fs pulse-width, is designed. The system output parameters were compared to spherical Offner configuration and is shown that the output pulse from the cylindrical Offner has much lower spatial chirp than Spherical Offner.
