AB  - We investigate the temporal precision in the generation of ultrashort<p>   laser pulse pairs by pulse shaping techniques. To this end, we combine a<p>   femtosecond polarization pulse shaper with a polarizer and employ two<p>   linear spectral phase masks to mimic an ultrastable common-path<p>   interferometer. In an all-optical experiment we study the interference<p>   signal resulting from two temporally delayed pulses. Our results show a<p>   2 sigma-precision of 300 zs = 300 x 10(-21) s in pulse-to-pulse delay.<p>   The standard deviation of the mean is 11 zs. The obtained precision<p>   corresponds to a variation of the arm's length in conventional delay<p>   stage based interferometers of 0.45 angstrom. We apply these precisely<p>   generated pulse pairs to a strong-field quantum control experiment.<p>   Coherent control of ultrafast electron dynamics via photon locking by<p>   temporal phase discontinuities on a few attosecond timescale is<p>   demonstrated.
