Abstract

As pulse duration is decreasing, it becomes mandatory to take into account the residual spectral phase that can't be corrected in CPA laser systems. Up to date CPA systems are well corrected for chirp (ϕ2) and ϕ3 [1]. The remaining spectral phase defect reduces the amplified pulse contrast. Furthermore, gain narrowing in Ti.Sapphire amplifier limits the pulse duration to 30fs. By controlling both spectral amplitude and phase we can reach pulses as short as 16fs
