Chirp compression with single chirped mirrors and its assembly

Chirped mirrors are widely used in ultrafast optics as broadband devices for dispersion compensation. Time domain analysis in contrast to frequency domain one allows the direct investigation of pulse profile changing during chirp compression. We model the chirped pulse compression with single chirped mirror and assembly of similar mirrors. Our analysis shows there is similar effect of chirp compensation in both cases. However, injurious group delay oscillations in the single mirror strongly decrease pulse quality in assembly of mirrors and can even damage pulse waveform. Angle of incidence and polarization also play crucial role and should be taken into account.
