According to the requirement of Ti: sapphire laser, the optimized chirped mirrors(CM) are designed to provide group delay dispersion (GDD) of around -60 fs2 with bandwidth 200 nm at a center wavelength of 800 nm. The CMs are manufactured by time controlled ion beam sputtering.The GDD is determined by using a home-built white light interferometer. The measurement results show that the manufactured CM can meat our requirement. By balancing the intra-cavity dispersion with our manufactured chirped mirrors, 12 fs and 9.5 fs pulses have been obtained respecitively.
