%X {We investigate the temporal precision in the generation of ultrashort
   laser pulse pairs by pulse shaping techniques. To this end, we combine a
   femtosecond polarization pulse shaper with a polarizer and employ two
   linear spectral phase masks to mimic an ultrastable common-path
   interferometer. In an all-optical experiment we study the interference
   signal resulting from two temporally delayed pulses. Our results show a
   2 sigma-precision of 300 zs = 300 x 10(-21) s in pulse-to-pulse delay.
   The standard deviation of the mean is 11 zs. The obtained precision
   corresponds to a variation of the arm's length in conventional delay
   stage based interferometers of 0.45 angstrom. We apply these precisely
   generated pulse pairs to a strong-field quantum control experiment.
   Coherent control of ultrafast electron dynamics via photon locking by
   temporal phase discontinuities on a few attosecond timescale is
   demonstrated. (C) 2011 Optical Society of America}
